Gravitational Potential Energy Calculator (Ep=mgh)
Compute gravitational potential energy via Ep = mgh: enter mass and height to get joules and the landing velocity.
Key points
Gravitational Potential Energy Calculator (Ep=mgh): Compute gravitational potential energy via Ep = mgh: enter mass and height to get joules and the landing velocity. Formula: Ep = m·g·h. Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Ep = mgh: potential energy equals mass × gravity × height; the reference level (zero) is arbitrary and cancels when taking differences. Conservation of mechanical energy: without friction, potential energy fully converts to kinetic energy, landing velocity v = √(2gh).
Inputs
