Sep 07,  · Gravitational Potential Derivation Its SI unit is J/kg and it is a scalar quantity Its dimensional formula is L² T 2 Since, work W is obtained, ie it is negative, the gravitational potential is always negative Gravitational potential energy of any object at any point in gravitational field is equal to the work done in bringing itAlternatives include storing energy by moving large solid masses upward against gravity This can be achieved inside old mine shafts or in specially constructed towers where heavy weights are winched up to store energy and allowed a controlled descent to release itFor convert gravitational energy into electric energy – the mass of bodies moves from the upper level to the lower – not in itself (and even – water), but in the conveyor Pplato Flap Phys 5 2 Energy Damping And Resonance In Harmonic Motion Gravitational potential energy storage with solid masses
