  1. Kinetic Energy:
    Kinetic Energy: the energy associated with moving objects. It is given by:

    Mechanical energy is conserved when the sum of kinetic and potential energies remains constant.
  3. Work-Energy Theorem:
    Relates the work performed by all forces acting on a body in a particular time interval to the change in kinetic energy at that time: 

    The expression is

  4. Conservation of Energy:
    When there are no nonconservative forces (e.g. friction) acting on a system, the total mechanical energy remains constant:
