Question

Derive the equation of kinetic energy half mv square

Answer 1

hello friend ✌️



Answer:  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


hope it's help you my friend ✌️✌️✌️
