This formula explicitly states a potential energy difference, not just an absolute potential energy. Therefore, we need to define potential energy at a given position in such a way as to state standard values of potential energy on their own, rather than potential energy differences.

Potential Energy Formula. The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is: W = m×g×h = mgh. Where, m is the mass in kilograms. g is the acceleration due to gravity. h is the height in meters. Potential Energy Unit.
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
If you know the potential energies (\(\mathrm{PE}\)) for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is: \[\mathrm{KE_i+PE_i=KE_f+PE_f.}\]
In terms of potential energy, the equilibrium position could be called the zero-potential energy position. There is a special equation for springs that relates the amount of elastic potential energy to the amount of stretch (or compression) and the spring constant.
21 lut 2022 · Potential energy is mechanical energy acquired by an object due to its position. It is stored energy that depends upon the relative position of the object and a reference point or level. Potential energy can be converted into kinetic energy and vice versa. It is a scalar quantity and a state function.
Relate the difference of potential energy to work done on a particle for a system without friction or air drag; Explain the meaning of the zero of the potential energy function for a system; Calculate and apply the gravitational potential energy for an object near Earth’s surface and the elastic potential energy of a mass-spring system
