Objectives: The objective for this lab was to address this question “Do objects at rest really remain at rest unless acted upon by external forces?”

Materials: Ramp, Cart, Wood, Table

Hypothesis: I think if you pull the ramp from underneath that the cart will fall onto the floor.

Procedures:

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 is the (art of the ramp that is over the table. The cart at this point is in a state of rest.

3. Standing to one side, quickly jerk the ramp out from underneath the Hall’s cart. Try this 4-5 times. Record your observations.

4. Analyze your results.

Data:

Trial 1: The cart did not fall or roll. It just slides onto the table backwards.

Trial 2: The cart did the same thing it in trial 1.

Trial 3: The cart slide off of the left side of the ramp.

Trial 4: The cart did the same thing it did in trial 1 & 2.

Conclusion: My hypothesis was somewhat correct. I predicted that the cart would fall off the ramp and onto the floor. In addition, the cart fell off the ramp; it did not fall onto the floor. The cart did not follow Newton's first law for a body at rest. Displayed by data, the cart did not stay at rest. The car moved only when applied a certain amount of force.
