Potention energy function
Potential energy is the energy by virtue of an object's position relative to other objects. [6] Potential energy is often associated with restoring forces such as a spring or the force of gravity. The action of stretching a spring or lifting a mass is performed by an external force that works against the force field … See more 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. The term potential energy was introduced by the 19th-century … See more There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the … See more For small height changes, gravitational potential energy can be computed using In classical physics, gravity exerts a constant downward force F = (0, 0, Fz) on the center of mass of a body moving near the surface of the Earth. The work of gravity on a body … See more The potential energy is a function of the state a system is in, and is defined relative to that for a particular state. This reference state is not always a real state; it may also be a limit, such as with the distances between all bodies tending to infinity, provided … See more Potential energy is closely linked with forces. If the work done by a force on a body that moves from A to B does not depend on the path … See more A horizontal spring exerts a force F = (−kx, 0, 0) that is proportional to its deformation in the axial or x direction. The work of this spring on a body moving along the space curve s(t) = (x(t), … See more The electrostatic force exerted by a charge Q on another charge q separated by a distance r is given by Coulomb's Law The work W required to move q from A to any point B in the … See more Web12 Sep 2024 · In the electric field of the proton, the potential energy of the electron is \[U(r) = -k\frac{e^2}{r}, \nonumber \] where \(k = 1/4\pi\epsilon_0\) and \(r\) is the distance …
