What must be true of an object that has gravitational potential energy?

it is stretched beyond a certain length.
it is above a reference point.
it is compressed shorter than a given length.
it is moving past a reference point.

B because gravitational potential energy is created when an object has the potential to fall, like if you hung something from your ceiling, the reference point would be your floor

It is above a reference point.

Explanation:

The reference point at which the gravitational potential energy is zero can be chosen arbitrarily. Thus, the potential energy at a height h above that reference point is equal to the work that would be required to raise the object to that point without net change in its kinetic energy.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i think the answer would be reserve.
