1 1.Action and reaction forces comprise the parts of A) A single interaction B) Two interactions 3 rd Law Questions

2 2.A player catches a ball. Consider the action force to be the impact of the ball against the players glove. The reaction to this force is the A) players grip on the glove B) Force the glove exerts on the ball C) Friction of the ground against the players shoes D) Muscular effort in the players arms E) None of these 3 rd Law Questions

3 3.Earth pulls on the moon. Similarly the moon pulls on the Earth, evidence that the A) Earth and moon are simply pulling on each other. B) Earths and moons pulls comprise an action-reaction pair. C) Both of these D) Neither of these. 3 rd Law Questions

4 4. 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 A) Air resistance on the ball B) Weight of the ball C) Force of the ball against the bat D) Grip of the players hand against the ball E) None of these 3 rd Law Questions

5 5. A baseball player bats a ball with a force of 1000 N. The ball exerts a reaction force against the bat of A) Less than 1000 N B) More than 1000 N C) 1000 N 3 rd Law Questions

6 6. A person is attracted toward the center of the Earth by a 500-N gravitational force. The force of attraction of the Earth toward the person is A) very, very small B) Very, very large C) 500 N 3 rd Law Questions

7 7. The attraction of a persons body toward the Earth is called weight. The reaction to this force is A) The persons body pushing against the Earths surface B) Earths surface pushing against the persons body C) The persons body pulling on the Earth D) None of these 3 rd Law Questions

8 8. The force exerted on the tires of a car to directly accelerate it along a road is exerted by the A) Engine B) Tires C) Air D) Road E) None of these 3 rd Law Questions

9 9. A horse exerts 500 N of force on a heavy wagon. The wagon pulls back on the horse with an equal force. The wagon still accelerates because A) These forces are not an action-reaction pair B) Nevertheless there is still an unbalanced force on the wagon C) The horse pulls on the wagon a brief time before the wagon reacts D) Unlike the horse, it is not alive 3 rd Law Questions

10 10. 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 actually A) Less than 3000 N B) 3000 N C) More than 3000 N D) There is really no way to say for sure 3 rd Law Questions
