When a baseball player catches a ball, the ball pushes towards the glove; this is the action force. What is the reaction force?

• The reaction force is the glove pushing back on the ball with a stronger force.

• The reaction force is the glove pulling back on the ball with an equal force.

• The reaction force is the glove pushing back on the ball with an equal force.

• The reaction force is the ball pushing away from the glove with an equal force.

An ice skater pushes off a wall and glides backwards for a few meters and then stops.

Which statement best describes an action-reaction force pair in this statement?

• The friction of the ice decreases as the blade of the skate moves on the ice.

• The wall pushes on the skater as the skater pushes on the wall.

• The ice skates slow down, and the skater stops

• The skaters exerts a force on the wall, and blade exerts a force on the ice.
