Four different students take turns pushing a large, heavy ball on the school parking lot. What is the best way to determine which student used the most force to push the ball?

• compare the sizes of the students

• compare the ages of the students

• compare the distances that the ball rolled

• compare the number of times the ball was rolled

When is friction needed during the course of motion?

• to speed up motion

• to slow down motion

• to keep motion at the same speed

• to keep motion at the same speed

In a science lab, students measured how long it took for a block to slide down a ramp.

Test Number Condition of the Ramp

1 The ramp was not covered.

2 The ramp was covered with waxed paper

3 In the third test, the ramp was covered with sandpaper.

What were the students comparing in this experiment?

• the amount of frictional force acting on the block

• the amount of gravitational force acting on the block

• the amount of frictional force acting on the ramp

• the amount of gravitational force acting on the ramp
