Objects in Motion Remain in Motion

Experiment 3:

Objective: To prove that objects in motion don't continue to be in motion unless acted upon external force.

Hypothesis: I think that when you push the cart the 100 g mass will fall off of the cart.

Materials Used:

1. ramp
2. cart
3. tape
4. cardboard
5. 100g mass

Procedure:

1. Place the wooden ramp on the floor

2. Tape a piece of cardboard over the hole in the Hall's cart

3. Put the 100 g mass on top of the cardboard as illustrated

4. Gently push the cart so that it collides with the edge of the ramp. You must push the cart gently enough so that the mass does not move until the cart hits ramp.

Data:

Trial 1- 100g mass falls
Trial 2- 100g mass rolls on the board
Trial 3- 100g mass falls on the floor
Trial 4- 100g mass rolls on the floor

Conclusion:

1. It kept falling and/or rolling on to the ramp or the floor.

2. Yes, my hypothesis was correct

3. Yes, it follows Newton's First Law

4. Nothing really went wrong, except when we would collide the cart with the ramp it would fall and roll on the floor.

5. I couldn't see using this in a real word application

6. I learned that when driving always wear a seat belt.
