In all system changes energy is
WebIn Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is ΔU = mg(y2 −y1) Δ U = m g ( y 2 − y 1). This works very well if g does not change significantly between y1 y 1 and y2 y 2. We return to the definition of work and potential energy to derive an expression ...
