I How K= ∫mvdv = ∫m dx/dt dv ?

    In equation K= ∫mvdv = ∫m dx/dt dv, how can we write v at any time t as dx/dt?? Does it make any sense??

    This is how velocity is defined. How do you define velocity?

    Well, velocity is the rate of change of position (x) with respect to time (t). So v=dx/dt by definition.

    Yup I got it. Thanks
