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
Roche limit: The position about a massive body where the tidal forces because of the gravity of the primary equivalent or exceed the surface gravity of a particular satellite.
Example of like and unlike parallel forces
Universal constant of gravitation; G: The constant of proportionality in Newton's law of universal gravitation & which plays an vital role in A. Einstein's general relativity.
if the universal gravitational force depends on the product of the masses and depends on the distance between the masses ,find an expression for the universal force, and the unit f
