Find the kinetic energy of an object, given its mass and velocity. Find the kinetic energy of an object, given its mass and velocity.
Description : In physics, the kinetic energy of an object is the energy that it Description : In physics, the kinetic energy of an object is the energy that it
possesses due to its motion. It is defined as the work needed to accelerate a body of a possesses due to its motion.It is defined as the work needed to accelerate a body of a
given mass from rest to its stated velocity. Having gained this energy during its given mass from rest to its stated velocity.Having gained this energy during its
acceleration, the body maintains this kinetic energy unless its speed changes. The same acceleration, the body maintains this kinetic energy unless its speed changes.The same
amount of work is done by the body when decelerating from its current speed to a state amount of work is done by the body when decelerating from its current speed to a state

In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling
at a speed v is ½mv². In relativistic mechanics, this is a good approximation only when at a speed v is ½mv².In relativistic mechanics, this is a good approximation only when
v is much less than the speed of light. The standard unit of kinetic energy is the v is much less than the speed of light.The standard unit of kinetic energy is the
