Write a hypothesis for Part I of the lab, which is about the effect on an object being carried by a car, when the car experiences a sudden impact. Use the format of "if . . . then . . . because . . . ” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s first law.

Write a hypothesis for Part II of the lab, which is about the relationship described by F = ma. In the lab, you will use a toy car and apply forces to it. Use the format of "if . . . then . . . because . . .” and be sure to answer the lesson question "How can Newton's laws be experimentally verified?” specific to Newton’s second law.
If force is applied to a car, then its acceleration will change proportionally, as predicted by Newton’s second law, F = ma.
