to help you understand the concept of action and reaction.
Question 1
1.
An archer shoots an arrow. The action force is the bowstring against the arrow. The reaction force is-
air resistance against the bow.
arrow's push against the bowstring.
grip of the archer's hand on the bow.
Question 2
2.
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.
Question 3
3.
A player bats a ball with a force of 1,000 N. The ball exerts a reaction force against the bat of-
