Objective: The objective of theis experiment was to test Newton's Second Law. It was also to find out if increasing the force on an object increase the accelerstion of the object.

Hypothesis: I think that as we add the washers to the paperclip hook the Hall's cart will slow down.

Materials:
steel rod
piece of string [1m long]
paper clip
Hall's cart
100g mass
washers


Procedure:
1. Tape the steel rod to the edge of a table so that it is directly over the edge. This will act to feduce friction in the experiment.
2.Cut a piece of string 1 meter long. Attach one end of the string to the Hall's cart using a paper clip.
3. Open up a paper clip to form a loop on one end and hook on the other. Tie the loop end of the paper clip to the free end of the string.
4. Put the cart on the table about 3/4 of a meter from the rod and hang the end of the paper clip over the rod. Put the 100g mass in the cart.
5. Add thw washers to the paper clip hook one at a time until the cart begins to move. Carefully observe the speed of the cart as it moves along the table. Repeat 4-5 times and record the number of washers used each time.
6. Repeat step 5, but this time double the force by doubling the number. Observe the speed and acceleration of the cart carefully. Repeat several times. Record your results.
7. Repeat step 7, but this time triple the number of washers used in step 5. Observe the speed and acceleration of the cart carefully. Repeat several times. Record your results.


Data:
-SINGLE
Washer[s] 1- No Motion
Washer[s] 2- No Motion
Washer[s] 3- No Motion
Washer[s] 4- No Motion
Washer[s] 5- Moved at a constant speed to the floor.

-DOUBLE
Washer[s] 2- No Motion
Washer[s] 4- No Motion
Washer[s] 6- Moved at a slow motion.

-TRIPLED
Washer[s] 3- Moved very slowly.
Washer[s] 6- Moved at an constant speed.
Washer[s] 9- Moved very quickly.



Graphs/ Pictures:







Equations:
-f=ma
-1 meter= 39.4 in.
Conclusion: It takes more force to accelerate the cart quickly. In that case my hypothesis was incorrect. AAAWWWW!!! As I added the paper clips the cart moved faster. This experiment does regard Newton's Second Law.

Objective: The objective of this experiment has to do with the force required to change the speed or direction of a moving object. It also was see if it takes more force to change the speed or direction of a moving object than it does to maintain the initial speed of the object.

Hypothesis: I think the same force required to accelerate an object is the same to change the direction of an object.

Materials:
8" string
Hall’s cart
200g mass
string scale

Procedure:
1. Cut a piece of string about 8" long.
2. Tie one end to the front of the Hall’s cart and tie a loop in the free end.
3. Put the 200g mass in the Hall’s cart.
4. Zero the spring scale and attach the hook on the spring scale to the string loop on the cart.
5. Start moving at a slow speed by pulling on the string scale.
6. Then quickly pull harder to accelerate the speed of the cart. Repeat this five times and record the maximum force reading on the spring scale each time.
7. Experiment with changing the direction of the cart. Start the cart rolling slowly by pulling on the spring scale and then pull the scale in a wide are to change the direction of the cart. Try this five times changing direction as quickly as you can without tipping the cart over. Record the maximum force to change direction each time.

Data:
Straight...
Trial 1: 1 N 100g
Trial 2: 1 N 100g
Trial 3: 0.5 N 50g
Trial 4: 1.3 N 130g
Trial 5: 1.5 N 150g

Changing Direction...
Trial 1: 0.5 N 50g
Trial 2: 1.6 N 160g

Trial 3: 1 N 100g
Trial 4: 1.4 N 140g
Trial 5: 1.3 N 130g

Graphs/ Pictures:







Conclusion: In conclusion my hypothesis was kind or correct. My readings of the spring scale were not constant when the Hall’s cart was pulled straight or when it was changing its direction. In both areas they had at least two of the same forces but in different trials. I learned in this experiment that it takes almost the same to change the direction and to increase the speed.

Objective: The objective of this project was test to Newton’s first law with respect to objects on motion. It was also to see if objects in motion really continue in motion unless acted by an external force.

Hypothesis: I think that the 100g mass will fall off of the Hall’s cart.

Materials:
wooden ramp
tape
cardboard
Hall’s cart
100g mass

Procedure:
1. Place wooden ramp on the floor.
2. Tape a piece of cardboard over the hole in the Hall’s cart.
3. Put the 100g mass on top of the cardboard as illustrated.
4. Gently push the cart so that it collides with the edge of the ramp. [make sure you push the cat gently enough so that the mass does not move until the cart hits the ramp]
5. Repeat steps 1-4 four times.

Data:
Trial 1- The 100g mass moved forward
Trial 2- The 100g mass fell off backwards
Trail 3- The 100g mass moved forward
Trial 4- The 100g mass fell off forward

Graphs/Pictures:








Conclusion: As a result my hypothesis was correct. Even though every time I did steps 1-4 I had a different reaction. On trails two and four the 100g mass fell off. At least from this experiment we know that the cart is acted upon external force of the ramp because of how the 100g mass reacted to it. This experiment did not follow Newtons first law. When the cart was acted upon by the wooden ramp, it stopped.

Objective: The objective of this experiment was to determine how the force is required to start moving a stationary object compared to the force to keep an object moving.

Hypothesis: I think that the cart will require more force from rest than from moving.

Materials:
8" long string
Hall's cart
200 gram mass
Spring Scale

Procedure:
1. Cut a piece of string about 8" long.
2. Tie one end to the front of the Hall's cart and tie a loop in the free end.
3. Put the 200 gram mass in the Hall's cart.
4. Push the cart back and forth on the table.
5. Zero the spring scale and attach the hook on the spring scale to the spring loop on the cart.
6. Tug on the spring scale several times to start the cart moving from rest. Record the readings.
7. Now, jerk on the spring scale several times to rapidly start the cart moving rest. Record the readings.
8. Finally, pull the cart across a table or floor at a constant speed several times. Record the readings.
9. Repeat steps 1-7 four times.

Data:
TUG...
Trial 1= 0.1 N, 10g
Trial 2= 0.2 N, 20g
Trial 3= 0.3 N, 30g
Trial 4= 0.3 N, 30g

JERK...
Trial 1: 2.2N, 220g
Trial 2: 1.5N, 150g
Trial 3: 1.3N, 130g
Trial 4: 1.3N, 130g

CONSTANT...
Trial 1: 0.3N, 30g
Trial 2: 0.3N, 30g
Trial 3: 0.3N, 30g
Trial 4: 0.3N, 30g

Graphs/Pictures:






Conclusion: In conclusion starting an object at rest takes more force. Is also takes more force to start an object moving. So my hypothesis was correct. I also do noy think that this follows Newton's first law of motion.

Objective: The objective of this experiment is to find out if objects at rest remain at rest unless acted upon by external forces.

Hypothesis: I think that if we pull the ramp out from underneath the cart, the cart will slide backwards.

Materials:
1 wooden cart
12" ruler
Halls Cart

Procedure:
1. Set the wooden ramp on a table with about 12" of the ramp extending over the edge of the tables.
2. Place the Hall's cart pm, the art of the ramp that is over the table.
3. Standing to one side, quickly jerk the ramp out from underneath the Hall's cart. Record the readings.
4. Repeat steps 1-7 four times.

Data:
Trial 1= The Hall's cart fell back just a little.
Trial 2= The Hall's cart stayed in the same position.
Trial 3= The Hall's cart moved a little when jerked.
Trial 4= The Hall's cart moved forward.

Graphs/ Pictures






Conclusion: In conclusion when the cart was removed the four different times, they each had a different reaction. So on that note my hypothesis was correct, the first trial the Hall's cart moved backwards. As a result this experiment does not follows Newton's first law for body at rest.

UTOPIAN DEBATE [ARCHITECTURE]

In this thread you must discuss Architecture. What style of housing would you use? Is "row housing" the best way to organize housing? What types of materials would be used? Wood? Stone? Brick? Mud?You must discuss the reason why you chose the materials. Is it bio-degradable?

You must respond to the ideas of at least four of your cohort (group) members.

In my utopian society everyone would be able to have their own style of house but in the same aspect. For example, everyone will have nicely cut lawns with neatly planted flowers, a two car garages, four exits, nicely stoned and glass walls. But one neighbor might want to have a differnt amount of bed rooms or bathrooms. Or they might want to add extra rooms like a movie room or a game room. I choose my house to be made out of these materials so my society will not look like the typical society with a house made from bricks. My society will be differnt and unique. In my opinion row housing is the best way to organize your housing but its plain, boring and corney. Everyones house will be connceted to gether looking the same. Someone might mistake someone elses house for their own [lol]. But with my unique way of housing in my neighborhood you cannot go wrong. Also there was a question asking if it will be bio-degradable. No. My house will not be bio-degradable, it will not be capable of being, broken down by bacterial and fungi.



- I disagree with pretty boi. Row housing is CORNEY. No-one wants to come into a neighborhood with everything looking the same. eventually it will become tiring.

- I disagree with yaya. If you just have condos people might feel uncomfortable. What is someone in your neighborhood wants to live some place small?

- I definietly disagree with ant dollas. No-one wants to live in a house with tented windows. This is not the hood and it is not your car.

- I do agree with tiffy pooh. I would love to live in her neighborhood it would seem fun and exciting.

MORAL RESPONSIBILITY

In the words of Dr Martin Luther King Jr, "There is nothing in the world more dangerous than sincere ignorance and conscientious stupidity. You have a moral responsibility to be intelligent."

Your assignment is this simple: You are to compose a clear, concise 5 paragraph essay AGREEING or DISAGREEING with this quote. You are to utilize the methods taught to you in M. Shakae's class regarding the 5 paragraph essay and 3 POINT THESIS, INCLUDING supporting details. This essay is due by the close of the day on Friday, March 28th.



“There is nothing in the world more dangerous than sincere ignorance and conscientious stupidity. You have a moral responsibility to be intelligent,” said Dr. Martin Luther King Jr. I would have to say that I agree with his powerful quote. It is basically saying God gave you a brain and it is due to you to use it. People who have moral responsibility reflect on their situation, form intentions about how they could change their act, and carry out that action.

From my viewpoint in order for you to be morally responsible you need to reflect on your situations. As proof you could not be morally responsible if you do something negative and it has no effect on you what so ever. For example, I told my mom that I would clean the kitchen after I finished my homework. Despite of doing what I told her that I would do I decided to go to my friend Gina’s house to see her new puppy. Obviously when my mom came home she was very upset and disappointed. Afterwards I felt bad about lying to my mom. Me thinking about what I did wrong showed that I was morally responsible.

Furthermore I tried to figure out a plan to make my mom feel better. Not only that I wanted her to know that the next time I told her I would do something that I actually would do it. As I sat in the kitchen and cleaned it as much as I possibly could I carefully tried to map out my plan. At first I thought about just pleading to her how much I was vas sorry, but decided against it. I finally thought that if I just cleaned the entire house she would understand that I felt how ignorant and stupid my actions were. That is to say my strategy to reverse the situation showed that I was morally responsible.

Indeed that was exactly what I did. I carried out my action to clean my entire house. Not to mention I even cleaned my little brothers room in which was extremely disgusting. Towards the end, my mom noticed how much I was struggling since I had never worked this much in my entire 16 years I have been living. She said that she appreciated the fact that I tried to make the situation better. Not only did I do something negative but I worked very hard to make it positive and showed that I was morally responsible.

In the long run in order to have moral responsibility you need to think about your position, put your mind towards a change and just do it. You are morally responsible for being bright and clever. If you are in a situation where you know that your wrong try to make it right. Show everyone that you have a mind that you use wisely and that you are not ignorant. It is always said that the mind is a terrible thing to waste.

UTOPIAN DEBATE [SOCIETY]

Scenario: The United Nations begins planning the Utopian society. There are many nations represented. Answer the following questions:
- Where will the Utopia society exist?
- What about the people who live there already? Should they be moved? Will that cause a problem?


I believe that the utopian society should be everywhere. Everyone should pick a place it is that they will feel at peace and live there. This would be the best way to obtain a utopian society because the place you pick you would be around the same people who like whatever it is that you like. Everyone would have to move depending on their likes. But this will not cause a problem because in the end everyone will have a place to live and be satisfied.

UTOPIAN DEBATE

This thread will allow you all to respond and debate with one another. You must not only respond to the question, but you must also respond to the comments that are on the blog. For this assignment you must respond to four comments that have been posted by your classmates.

Question: Should there be laws in a utopian society?


I believe that there should be laws because there would be too much chaos and confusion.

-With what Tiffy Pooh said. How could there be perfection with all of the crime and murders. Those people should be punished not let go free and say dont do it again.

-I strongly agree with mzernell. There will be no morals or guidelines to follow so no type of work would be able to get done.

-I disagree with yaya. A utopia is suppose to be free-spirited and open but if there are not any rules than there would be no direction.

5 PARAGRAPH ESSAY FOR UTOPIAN SOCIETY

Live, laugh, love! Meaning you have to live your life to the fullest, laugh often and love unconditional. In doing so you should live your life everyday like it was your last. If everyone were like this in his or her country, state, city, and community it will be perfect, just as in a Utopian society. In it has perfect political and social order, it seems close but is really very far. We could live in a Utopian Society if we had \understnding, appreciation, and fairness.

To begin with society needs to be more understanding. We need to understand that everyone was given the freedom of speech. This is to say that everyone should be able to voice their own opinion without it being held against them. For example, Dr. Martin Luther King Jr. He voiced his opinion about African- American civil rights. When people did not agree on what he said, he was assassinated. If the society would have had an open mind about what he was saying and understand him, things could have went differently.

On top of that we need to learn how to appreciate. In other words if we learn how to be grateful for what we were given instead of worrying about what we do not have or what the next person has that we do not, we could be one step closer to attaining the Utopian Society. For example, if you and your next-door neighbors house has the same outline but your neighbors’ home is more furnished. Instead of your being upset about whose house looks better, be grateful and appreciate that you even have a house to lay your head down in. Be mindful, there are so many people that do not even have a house to begin with let alone try to be mad about furniture.

Not to mention society needs to understand that every man was created equal, no matter what the race, color or nationality they are. Therefore all rules should apply to everyone; there should not be different standards for different nationalities. For example, when going to war everyone will fight no matter what the color of their skin is. They will make sure that they have someone to have their back to win. If we put that energy that we put into fighting and going to war towards strengthening and organizing our society it could become Utopia.

Eventually, we could attain a Utopian Society if we have a Utopian Society if we understand and appreciate one another and treat each other fairly. If we come together and become opinionated and equally treated we can try to form our own Utopia. One by one we can come together to help our society to be perfect, or we can at least try. I will be the first to stand. From this day forward I will live my life to the fullest, laugh often, and love unconditionally.

EGG DROP DESIGN

View the design above. discuss the pros and cons of the design. You may respond to other posters comments.

I must admit this egg crate is very creative. It was created so the egg is directly in the middle. Around it are many straws for the cushion. They will protect they egg in a free fall. On the other hand what if the crate was to tip over in while participating in the free fall. The egg will be able to fall out if the top of its crate and break.
