A book on the
top shelf of a locker possesses mechanical energy due to its vertical position
above the ground (gravitational potential energy).
 B.
Potential energy
This is the
stored energy of position possessed by an object.
Mathematically the
potential energy of an object is:
Where,
m represents the mass of
object (Kg), h represents
the height of the object (metres), g
represents the acceleration of gravity (9.8 m/s2 on Earth) and PEGR
represents the potential energy
(Joule, J).
Where,
ME represents the mechanical
energy, KE represents the
kinetic energy and PE represents the potential energy.
