**In physics, the kinetic energy of an object is the energy that it possesses due to its motion.
**

Physics is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms.

**It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. **

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.

M is the thirteenth letter of the modern English alphabet and the ISO basic Latin alphabet.

**Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. **

In everyday use and in kinematics, the speed of an object is the magnitude of its velocity ; it is thus a scalar quantity.

**The same amount of work is done by the body when decelerating from its current speed to a state of rest.

**In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is

In physics, classical mechanics is one of the two major sub-fields of mechanics, along with quantum mechanics.

**. In relativistic mechanics, this is a good approximation only when v is much less than the speed of light.
**

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.

**The standard unit of kinetic energy is the joule.**

The joule, symbol J, is a derived unit of energy in the International System of Units.
