Question

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

Answer 1

Elastic potential energy is the energy that is stored by the forces within a distorted elastic object

Answer 2

Answer: C) elastic potential

Step-by-step 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:

`E.P.E = (1)/(2)kx^2`

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