Students conducted an experiment by stretching the same rubber band to various lengths, releasing it, and measuring how far it traveled. Based on the chart, what conclusion can be drawn?

• The more mass that a rubber band has, the more difficult it is to move.

• The shorter the length of a rubber band, the less energy can be stored in it.

• The more potential energy put into a rubber band, the more kinetic energy released.

• The farther a rubber band travels, the less it can be stretched later on.
