Let the initial velocity of the object be u. Let an external force be applied on it so that gets displaced by distances and its velocity becomes v. In this scenario, the kinetic energy of the moving body is equal to the work that was required to change its velocity from u to v. thus, we have the velocity-position relation as: V² = u² + 2as
