define kinetic energy. |
|
Answer» Inphysics, thekinetic energyof an object is theenergythat it possesses due to itsmotion.It is defined as theworkneeded to accelerate a body of a given mass from rest to its statedvelocity. Having gained this energy during itsacceleration, 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 of rest.Common symbols KE,Ek, or TSIunit joule(J)Inclassical mechanics, the kinetic energy of a non-rotating object .object ofmassmtraveling at aspeedvis1/2 mv^2 Inrelativistic mechanics, this is a good approximation only whenvis much less than thespeed of light.The standard unit of kinetic energy is thejoule. |
