Force & Motion Test Review

An object is moving with a speed of 12 meters/second in a straight line. What will be the

distance traveled by the object in 5 seconds?

(distance = speed × time)

• 2.4 meters

• 7 meters

• 17 meters

• 60 meters

What happens to the speed of an object when the position does not change over a period

of time?

• speed increases

• speed decreases

• speed remains zero

• speed changes uniformly

A student claims that gravitational force affects the motion of every object on Earth. Which

statement best supports this claim?

• A toy car stops rolling after traveling a distance.

• A ball falls to the ground when dropped from a height.

• A box needs more force to be pushed across a rough surface.

• A bicycle moves forward when a force is applied to the pedals.

Robby has two toy trucks. His red truck has a higher mass than his blue truck. What will

he have to do to make the two trucks go the same speed?

• He can push both trucks with the same force for the same period of time.

• He can push both trucks with the same force, but he will have to push the red truck for

  a longer time.

• He can push both trucks for the same amount of time, but he will have to push the red

  truck with more force.

• He can push both trucks for the same amount of time, but he will have to push the

  blue truck with more force.

Which best explains what happens to the speed of a toy car as it rolls

across a flat surface covered in carpet?

• It increases in speed because of friction.

• It decreases in speed because of friction.

• It increases in speed because of the force of gravity.

Sara rolled a basketball across some flat ground and noticed the ball

slowed down and eventually stopped. Which best explains why the

basketball stopped rolling?

• The force of friction pulled on the basketball.

• The force of gravity on the basketball increased.

• The size of the basketball decreased as the ball rolled.

• The mass of the basketball increased as the ball rolled.

• When objects pull towards each other

• When objects move away from each other

Which most affects a baseball’s motion when it is hit by a batter?

• The mass of the batter and how high the ball was thrown

• The mass of the batter and how fast the ball was thrown

• The angle of the baseball and how hard the batter hits it
