Mechanical energy E of particle, system or object is explained as the sum of kinetic energy K and potential energy U, i.e. E = K + U. It is a scalar quantity having dimensions [ML2T-2] and SI unit joule.
(i) It relays on frame of reference.
(ii) A body may have mechanical energy without having either kinetic energy or potential energy. Though, if both potential and kinetic energies are zero, mechanical energy will be zero. The result may or may not be true, i.e., if E = 0 either both KE and PE are zero or PE negative and KE positive such that KE + PE = 0

The record for the highest speed achieved in laboratory for a uniformly rotating object was 2.01*10^3 m/s for a0.15-m long carbon rod. What was the period of rotation of the rod?
Speed of light (in vacuo); c The speed on which electromagnetic radiation propagates within a vacuum; it is described as 299 792 458 m/s.
Energy: The term energy may be defined as the capacity for doing work. There are two forms of energy: potential energy and kinetic energy. POTENTIAL ENERGY Potential e
