Here the initial kinetic energy is zero, so thatΔKE=12mv2ΔKE=12mv2. The equation for change in potential energy states that ΔPEg=mgh. Sincehis negative in this case, we will rewrite this as ΔPEg= −mg|h|to show the minus sign clearly. Thus, −ΔPEg= ΔKE becomesmg|h|=12m...
For a spring, potential energy is calculated based onHooke's Law, where the force is proportional to the length of stretch or compression (x) and the spring constant (k): F = kx. Thus, the equation for elastic potential energy is PE = 0.5kx2...
