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.
