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
