A snowball sits at the top of a 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

Students conducted an experiment by stretching rubber bands and releasing them at different lengths. 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 rubber band, the less energy can be stored in it

• The more a rubber band is stretched, the further it will travel

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