NEWTON'S THIRD LAW

Newton's Third Law States that..?

• Objects in motion stay in motion and objects at rest stay at rest.

• Force is equal to mass times acceleration.

• For each action, there is an equal and opposite reaction.

A player catches a ball. The action force is the impact of the ball against the player's glove. The reaction force is...

• The force the glove exerts on the ball.

• The player's grip on the glove.

• The friction of the ground on the player's shoes.

If a horse pulls on a wagon at rest, the wagon pulls back equally on the horse. Can the wagon be set into motion?

• Yes, because there is a net force acting on the wagon.

• Yes, because there is a time delay between action and reaction.

• No, because the forces cancel each other.

• Yes, because the horse's pull on the wagon is larger than the wagon's pull on the horse.
