Give an example in which energy produces a force that causes motion.

• pushing a box allow energy to move from your body give force to cause motion

• pushing a box but no movement because energy is there anyway

When a moving object ​ (a)   with a still object of a​ (b)   weight, the energy transfer can affect the objects' speeds ​ . When the ball collides with the pin, it​ (c)   energy. The pin weighs​ (d)   , so this energy makes it move ​ (e)   than the ball.

• collides

• different

• transfers

• less

• faster
