The energy possessed by a object by virtue of its motion is known as kinetic energy (KE).

The KE of a moving body is similar to the amount of work that must be given to bring a body from rest into the state of motion. Conversely, the value of work that we have to do in order to collect a moving object to rest is similar to the negative of the kinetic energy of the body, i.e., to call a moving object to rest is equivalent to the negative of the kinetic energy of the object. i.e., to bring a moving body to rest is similar to the negative of the kinetic energy of the object.
