What does it mean to say that a collision is a "mutual interaction"?

Only the moving object is an active participant in the collision.

Both objects experience a force during the period of contact.

The stationary object absorbs all the force without pushing back.

The larger object dictates the outcome of the collision entirely.

A moving cue ball strikes a stationary eight ball in a game of pool. According to the principle of mutual interaction, what happens at the moment of impact?

The cue ball exerts a force on the eight ball, but the eight ball does not exert any force back.

The eight ball exerts a force on the cue ball, causing it to slow down, but it does not experience a force itself.

Both the cue ball and the eight ball exert a force on each other simultaneously.

Force is not exerted; instead, momentum is instantly transferred from the cue ball to the eight ball.

The goalpost is passive because it is fixed in the ground and does not move.

The goalpost actively exerts a force back on the ball, causing it to bounce off.

The force is contained entirely within the moving soccer ball until it comes to a stop.

The goalpost only becomes active if the force from the ball is great enough to damage it.

The ball's own kinetic energy reverses its path.

The wall exerts a force on the ball.

The air pressure in front of the ball increases.

The ball is designed to be elastic.

That the heavier object always exerts a greater force.

That one object is active and the other is passive.

That both objects are active participants in the interaction.

That the total energy of the system must decrease after the impact.
