Which equation correctly represents the gravitational potential energy of a system?

A. GPE =

MIE

mv2

B. GPE = ME + } mv2

C. GPE = ME - 3 m2

3 m2 - ME

D. GPE =

Explanation:

The mechanical energy of an object is equal to the sum of kinetic energy and the potential energy. Let ME is mechanical energy, KE is kinetic energy then its potential energy PE is given by :

Since, KE = (1/2) mv^2

So, correctly represents the gravitational potential energy of a  .system
