hello dear
Explanation:
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 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.
SI unit: joule
Derivations from other quantities: Ek = ½mv2; Ek = Et + Er
Common symbols: KE, Ek, or T
