Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth's gravity. The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam. If an object falls from one point to another point inside a gravitational field, the force of gra… Witryna5 mar 2024 · Now in electrostatics, we have E = 1 4 π ϵ q r 2 r ^ for the electric field near a point charge, and, with E = − grad V, we obtain for the potential V = q 4 π ϵ r. In electromagnetism we have dB = μ I 4 π r 2 r ^ × ds for the contribution to the magnetic field near a circuit element ds.
