Physics Chapter 5

A baseball player bats a ball with a force of 1000 N. The reaction force that the ball exerts against the bat is

1000 N

A karate chop delivers a blow of 3000 N to a board that breaks. The force that acts on the hand during this event is

3000 N

A piece of rope is pulled by two people in a tug-of-war. Each pulls with 400 N of force. What is the tension in the rope?

400 N

A person is attracted toward the center of the Earth by a 500-N gravitational force. The Earth is attracted toward the person with a force of

500 N

A Mack truck and a Volkswagen traveling at the same speed have a head-on collision. The vehicle that undergoes the greatest change in velocity will be the

Volkswagen

Arnold Strongman and Suzie Small each pull pull very hard on opposite ends of a massless rope in a tug-of-war. The greater force is exerted by

both the same, interestingly enough

A player hits a ball with a bat. The action force is the impact of the bat against the ball. The reaction to this force is the

force that the ball exerts on the bat

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

force the glove exerts on the ball

For an action force, there must be a reaction force that

is exactly equal in magnitude

As a ball falls, the action force is the pull of Earth on the ball the reaction force is the

pull of the ball's mass on the Earth

The force exerted on the tires of a car to directly accelerate it along a road is exerted by the

road

The attraction of a person's body toward Earth is called weight. The reaction to this force is

the person's body pulling on the Earth

Earth pulls on the moon. Similarly the moon pulls on Earth, evidence that

these two pulls comprise an action-reaction pair
