Work Energy and Power

Work done by a constant force and a variable force; kinetic energy, work-energy theorem,
Notion of potential energy, potential energy of a spring, conservative forces: conservation of
mechanical energy (kinetic and potential energies); non-conservative forces: motion in a
vertical circle; elastic and inelastic collisions in one and two dimensions.


Work is related to force and the displacement over which it acts. Consider a constant force F acting on an object of mass m....
