8. the conservation of energy
... In the absence of friction the conservation of mechanical energy holds and U(x) + K = E Since the kinetic energy can not be negative, the particle can only be in those regions for which E - U is zero or positive. The points at which E - U = K = 0 are called the turning points. The potential energy c ...
