The energy stored in an object

Energy in motion

As the height of an object increases, the object's potential and kinetic energy ( increases / decreases ).

As the height of an object decreases, the object's potential and kinetic energy ( increases / decreases ).

As the mass or weight of an object decreases, the object’s potential and kinetic energy

( increases / decreases ).

True or False: Energy can be created.

True or False: Energy can be destroyed.

True or False: Energy is constantly changing FORM.
