Hey buddy here is ur answer !!!!
Kinetic energy :
From equations of motion, the relation connecting the initial velocity (u) and final velocity (v) of an object moving with a uniform acceleration a, and the displacement, s is But from
Newton’s second law of motion
F = m a
work done by the force, F is written as the following:
If the object is starting from its stationary position, that is, u = 0, then From work and energy theorem, work done is equal to the change in the kinetic energy of the object.
w = (1/2) mv^2
If u = 0,
the work done will be,
Thus the kinetic energy possessed by an object of mass, m and moving with a uniform velocity, v is
K.E = (1/2) mv^2
Answer:
the deviation formula of kinetic energy is - 1/2mv^2
hope it will help you ...
