• decreases

• stays the same

• not enough information

As temperature increases, molecules will:

• Move faster and gain kinetic energy

• Move slower and gain kinetic energy

• Move faster and lose kinetic energy

• Move slower and lose kinetic energy

1. As the puck falls, the amount of potential energy it has decreases. Why?

• It is lost to the air friction

• It is released as sound energy

• it is stored in the puck

• It is changed into kinetic energy

• decreases

• stays the same

• is nothing
