Detailed Solution

For conservative forces the sum of kinetic and potential energies at any point remains constant throughout the motion. This is known as law of conservation of mechanical energy. According to this law,

Kinetic energy + Potential energy = constant

or $∆ K + ∆ U = 0 o r ∆ K = - ∆ U$
