WebJan 6, 2024 · A simple definition of the potential energy of a system is the amount of work it can do because of the relative positions of its parts. So if a system has negative potential energy with respect to when the parts of the system are separated to infinity, then work must be put in by an external force in order to separate the parts to infinity. WebKinetic energy can never be negative. It is always greater than or equal to zero. The kinetic energy of a moving object equals one-half the product of its mass and the square of its velocity. Since the mass of an object can never be zero, the square of velocity makes the answer positive. Therefore, kinetic energy can never be negative.
