what is its use at work?
Generation of pumped-storage hydroelectricity also used to power clocks in which falling weights operate the mechanism.
Potential energy
Gravitational potential energy has a number of practical uses, notably the generation of pumped-storage hydroelectricity. For example, in Dinorwig, Wales, there are two lakes, one at a higher elevation than the other. At times when surplus electricity is not required (and so is comparatively cheap), water is pumped up to the higher lake, thus converting the electrical energy (running the pump) to gravitational potential energy. At times of peak demand for electricity, the water flows back down through electrical generator turbines, converting the potential energy into kinetic energy and then back into electricity. The process is not completely efficient and some of the original energy from the surplus electricity is in fact lost to friction.

Gravitational potential energy is also used to power clocks in which falling weights operate the mechanism. It's also used by counterweights for lifting up an elevator, crane, or sash window.
Roller coasters are an entertaining way to utilize pote
how long does a glider stay in the air They can tay airborne for hours by flying through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy. The most commonly used sources of rising air are what is gliding? It is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne where did it start? Germany's Weimar Republic. how does it soar? By flying through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy. what is this type of energy mentioned? Energy  held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
