• radiant energy

An example of chemical potential energy is the energy of:

• food on body

• a stereo playing music

• a moving arrow

The energy of a ball flying through the air is...

• both kinetic and potential energy

• only kinetic energy

• mostly sound and heat energy

An energy transfer occurs when:

• energy forms matter as in the formation of the universe

• one form of energy changes to another energy form in the same object

• the form of energy remains the same type but is moved from one object to another
