... If F = −∇V where V (x, y, z) is the potential energy function, then dT = −∇V · dr = −dV (total derivative). Hence dT + dV = 0 ⇒ d(T + V ) = dE = 0 This is the expression for conservation of energy. Note: Energy is not conserved if the forces felt by an object cannot be associated with a potential en ...
