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.

The variables for Part I of this experiment include whether or not the car hits the barrier and the distance that the washers travel. Use the drop-down menus to identify the independent and dependent variables.

Answers:
The independent variable, the one that is intentionally manipulated, is .:an encounter with the barrier
The dependent variable, the one that you measure the response in, is .:the distance traveled by the washer

✔ accelerateX deceleratehave constant velocity

Answers:
From point A to point B, the car will .:accelerate
From point B to point C, the car will .:have constant velocity
Assuming the washer on the car is not blocked by the book, once the car hits the book, the washer will still have .:velocity
This experimental design will examine Newton’s law.:first
