We can define potential energy as a form of energy that results from the alteration of its position or state. After understanding potential energy and potential energy definition, let us learn the formula, unit, and examples of potential energy.
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.
21 lut 2022 · Equation. The gravitational potential energy depends on two factors – the object’s mass and its height from Earth’s surface. Suppose an object of mass m is at a height h from the surface of the Earth. Then, the potential energy can be calculated from the following equation. P.E. = mgh. Where. m: mass of the object.
Potential energy is the stored energy of position possessed by an object. Gravitational Potential Energy. The two examples above illustrate the two forms of potential energy to be discussed in this course - gravitational potential energy and elastic potential energy.
This property allows us to define a different kind of energy for the system than its kinetic energy, which is called potential energy. We consider various properties and types of potential energy in the following subsections.
Potential Difference and Electrical Potential Energy. The relationship between potential difference (or voltage) and electrical potential energy is given by \[\Delta V = \dfrac{\Delta U}{q} \label{eq1}\] or \[ \Delta U = q \Delta V. \label{eq2}\]
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: \[\mathrm{KE_i+PE_i=KE_f+PE_f.}\]
