The wall pushes on the skater when the skater pushes on the wall.
The wall pushes on the skater when the skater pushes on the wall.

The wheels slow down, and the skater stops.
The wheels slow down, and the skater stops.

The skater exerts a force on the wall, and the wheels exert a force on the floor and begin to turn.
The skater exerts a force on the wall, and the wheels exert a force on the floor and begin to turn.

The friction of the floor decreases when the wheels roll on the floor.

Answer 1

1) The gym floor pushes up on the ball as the ball pushes down on the floor with an equal amount of force.

2) Action: The force of the bird on the fence post. Reaction: The force of the fence post on the bird.

3) The wall pushes on the skater when the skater pushes on the wall.
