What does the kinetic energy means physically?

Kinetic energy is of course the energy associated with the motion of an object relative to that of another, but that doesn't do justice to what it really “means physically”, as this question asks. read more

the energy of motion of a body, equal to the work it would do if it were brought to rest The translational kinetic energy depends on motion through space, and for a rigid body of constant mass is equal to the product of half the mass times the square of the speed. read more

Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. read more
