Force and Motion Review

What is a push or pull that can change an object's direction?

What law states that objects at rest stay at rest and objects in motion stay in motion unless acted upon by an outside force?

• Newton's Second Law

• Newton's First Law

• Newton's Third Law

• Law of Inertia

Motion is another way of referring to....

Two forces act on an object in opposite directions but no motion results. This is because the forces were....

• weak

• balanced

• unbalanced

• equal

Unbalanced forces will result in .....

The force that pulls all objects toward the center of the earth or toward each other is.....

The tendency for objects to resist a change in motion is....

• acceleration

• friction

• gravity

• inertia

The greater the mass of an object, the __________ the force required to change it's motion.

A soccer ball is kicked very hard and shoots across the grass. No other players intercept the ball, yet it eventually rolls to a stop. What force acted upon the ball to change its motion?

• inertia

• friction

• gravity

• mass
