THE WORK OF A FORCE, PRINCIPLE OF WORK AND ENERGY
... particles can be derived by integrating the equation of motion (F = ma) with respect to displacement. By substituting at = v (dv/ds) into Ft = mat, the result is integrated to yield an equation known as the principle of work and energy. This principle is useful for solving problems that involve forc ...

As an illustration, consider the motion of an object moving at constant speed in a circular path of radius R. Since the speed is constant, it is tempting to say that the velocity is constant, but this is ...
