What must be true of an object that has gravitational potential energy?
a. it is stretched beyond a certain length.
b. it is above a reference point.
c. it is compressed shorter than a given length.
d. it is moving past a reference point.

The correct choice mus be

B.It is above a reference point.

Gravitational potential energy is the energy possessed by an object when it is at some height relative to a reference point.

when an object is stretched beyond certain length it stores elastic potential energy and not gravitational potential energy

when an object is compressed beyond certain length it stores elastic potential energy and not gravitational potential energy.

when an object is moving, it has kinetic energy.

ill do it for 100, also this isnt 80 its 40
