It is given by: Total Mechanic Energy: Mechanical energy is conserved when the sum of kinetic and potential energies remains constant. 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 Conservation of Energy: When there are no nonconservative forces (e.g. friction) acting on a system, the total mechanical energy remains constant: Momentum: A vector quantity. It is given by: p = mv Elastic Collisions:  Target at rest... Conservation of Momentum: Conservation of Kinetic Energy: Completely Inelastic Collisions: Target at rest...
