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 it 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.

A snowball sits at the top of the hill. Which of the following changes will increase the kinetic energy of the snowball?

• Additional snow falls on the snowball, increasing its mass.

• The snowball is pushed and rolls down the hill, gaining speed.

• The weather warms and the snowball melts, decreasing its mass.

• The snowball is moved and now sits on a hill that is higher.
