e. 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. [ 1][ 2] The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, [ 3][ 4][ 5] although it has links to the ancient ...
In classical mechanics, the kinetic energy of a point object (an object so small that its mass can be assumed to exist at one point), or a non-rotating rigid body depends on the mass of the body as well as its speed. The kinetic energy is equal to 1/2 the product of the mass and the square of the speed.
The electric potential energy of a system of point charges is defined as the work required to assemble this system of charges by bringing them close together, as in the system from an infinite distance. Alternatively, the electric potential energy of any given charge or system of charges is termed as the total work done by an external agent in ...
Maxwell–Boltzmann. In physics (in particular in statistical mechanics ), the Maxwell–Boltzmann distribution, or Maxwell (ian) distribution, is a particular probability distribution named after James Clerk Maxwell and Ludwig Boltzmann . It was first defined and used for describing particle speeds in idealized gases, where the particles move ...
General. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy (which is measured by the position of the parts of the system) and the kinetic energy (which is also called the energy of motion): [ 1][ 2] The potential energy, U, depends on the position of an object subjected to gravity or some other ...
Equipartition theorem. Thermal motion of an α-helical peptide. The jittery motion is random and complex, and the energy of any particular atom can fluctuate wildly. Nevertheless, the equipartition theorem allows the average kinetic energy of each atom to be computed, as well as the average potential energies of many vibrational modes.
The minimum total potential energy principle is a fundamental concept used in physics and engineering. It dictates that at low temperatures a structure or body shall deform or displace to a position that (locally) minimizes the total potential energy , with the lost potential energy being converted into kinetic energy (specifically heat).
