Mila is studying mechanical energy. She tapes a dowel onto a desk. Then she puts a 12cm spring on the dowel. Next, she slips a foam ball onto the dowel. As she changes the length of the spring by compressing it, she releases the ball into the air. She does this several times.
What happens to the ball as Mila changes the length of the spring?
When the spring is longer, the ball travels further.
When the spring is longer, the ball does not move.
When the spring is shorter, the ball travels farther.
Wen the spring is shorter, the ball does not move.
