16 Facts About Kinetic energy

Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time.

Standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound.

Kinetic energy can be transferred between objects and transformed into other kinds of energy.

For example, a cyclist uses chemical Kinetic energy provided by food to accelerate a bicycle to a chosen speed.

The chemical energy has been converted into kinetic energy, the energy of motion, but the process is not completely efficient and produces heat within the cyclist.

The kinetic energy has now largely been converted to gravitational potential energy that can be released by freewheeling down the other side of the hill.

The Kinetic energy is not destroyed; it has only been converted to another form by friction.

In inelastic collisions, kinetic energy is dissipated in various forms of energy, such as heat, sound and binding energy .

Several mathematical descriptions of kinetic energy exist that describe it in the appropriate physical situation.

Translational kinetic energy, that is the kinetic energy associated with rectilinear motion, of a rigid body with constant mass, whose center of mass is moving in a straight line with speed, as seen above is equal to.

When discussing movements of a macroscopic body, the kinetic energy referred to is usually that of the macroscopic movement only.

The kinetic energy of the system in the center of momentum frame is a quantity that is invariant .

At a low speed, the relativistic kinetic energy is approximated well by the classical kinetic energy.

So, the total energy can be partitioned into the rest mass energy plus the Newtonian kinetic energy at low speeds.

Kinetic energy can be expressed as the total energy minus the rest energy:.

For one particle of mass m, the kinetic energy operator appears as a term in the Hamiltonian and is defined in terms of the more fundamental momentum operator.
