Potential energy is the energy by virtue of an object's position relative to other objects. [5] 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 of the potential.
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2]
potential energy: joule (J) internal energy: joule (J) relativistic mass: kilogram (kg) energy density: joule per cubic meter (J/m 3) specific energy: joule per kilogram (J/kg) voltage also called electric potential difference volt (V) volume: cubic meter (m 3) shear force: velocity: meter per second (m/s)
Energy profiles describe potential energy as a function of geometrical variables (PES in any dimension are independent of time and temperature). H+H2 Potential energy surface. We have different relevant elements in the 2-D PES: The 2-D plot shows the minima points where we find reactants, the products and the saddle point or transition state.
A thermodynamic potential (or more accurately, a thermodynamic potential energy) [1] [2] is a scalar quantity used to represent the thermodynamic state of a system.Just as in mechanics, where potential energy is defined as capacity to do work, similarly different potentials have different meanings.
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.

The electrostatic potential energy U E stored in a system of two charges is equal to the electrostatic potential energy of a charge in the electrostatic potential generated by the other. That is to say, if charge q 1 generates an electrostatic potential V 1 , which is a function of position r , then U E = q 2 V 1 ( r 2 ) . {\displaystyle U ...
