What is the best description of the energy stored in a stretched or compressed object?
a)gravitational potential
b)potential energy
c)elastic potential
d)spring constant

C) elastic potential

Explanation:

A body possess potential energy by virtue of its position. It could be gravitational potential energy or elastic potential energy.

A body has gravitational potential energy due to its height above the surface of the Earth.

It is given by:

G.P.E. = m g h

where m is the mass, g is the acceleration due to gravity and h is the height.

A body has elastic potential energy when it is stretched or compressed. It is due to its elasticity which determined by spring constant.

It is given by:

where k is the spring constant and x is the extended or compressed length.

c.the charges if the proton and electron and gravity
