The forces are balanced.

The forces are balanced, and Team A is exerting a greater force.

The forces are unbalanced, and Team A is exerting a greater force.

The forces are unbalanced, and Team B is exerting a greater force.

The rocket moves upward as the fuel burns downward.

(Action/reaction)

The rocket remains stationary as the fuel burns.

(Stationary/action)

The rocket moves downward as the fuel burns upward.

(Reaction/action)

The rocket moves in a circular path as the fuel burns.

(Reaction/cycle)

The force applied to the bat by the player.

The force exerted from the pitcher that threw the ball.

The force of the ball on the bat.

The force that pulls the ball toward the ground.

When the car reaches the bottom of the hill, the kinetic energy and potential energy decrease.

When the car is at the top of the hill, the potential energy is the greatest and the kinetic energy is the least.

When the car goes down the hill, the potential energy increases and the kinetic energy decreases.

As the car moves up the hill, the kinetic energy increases, and the potential energy decreases.

The elastic potential energy of the compressed spring increased.

The elastic potential energy of the stretched spring increased.

The elastic potential energy of both springs increased.

The elastic potential energy of both springs decreased.
