Definition Of Kinetic Energy Method
The kind of motion may be translation rotation about an axis vibration or any combination of motions.
Definition of kinetic energy method. 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 the same amount of work is done by the body when decelerating from its current. K mv 2. In physics the kinetic energy ke of an object is the energy that it possesses due to its motion. Thomas young 1773 1829 derived a similar formula in 1807 although he neglected to add the to the front and he didn t use the words mass and weight with the same precision we do nowadays.
Thus an object s kinetic energy is defined mathematically by the following equation. Naturally the kinetic energy of an object at rest should be zero.
