### Carlos Ruiz catches a ball in the World Series. Consider the action force to be the impact of the ball against Ruiz's glove. The reaction force is: a) Ruiz's grip on the glove b) Force the glove exerts on the ball c) Friction of the ground against Ruiz's shoes d) Muscular effort in Ruiz's arm e) None of these

b) Force the glove exerts on the ball

b) 5N upward

c) Both the same

c) Same for both

a) Yes

a) A

c) Weight

### As a ball falls, the action force is the pull of the Earth's mass on the ball. The reaction force is the: a) Air resistance acting against the ball b) Acceleration of the ball c) Pull of the ball's mass on the Earth d) None of these

c) Pull of the ball's mass on the Earth

### Your teacher challenges you and your best friend to each pull on a pair of scales attached to the ends of a horizontal rope, in tug-of-war fashion, so that the readings on the scale will differ. Can this be done?

No- each scale will read half the amount of weight you are putting on it
