(PE2 - PE1) =![]()
It is followed that,
P.E.= -![]()
Thus , the conservative force field is expressible in the form of negative gradient of potential energy.
Principle of total minimum Potential Energy |
The change of potential energy PE of a particle between position 1 and 2 equals the negative of the work done by the conservative force as the particle moves from position 1 to 2, |
