### More on work and conservation of energy (7)

Physics: Kinetic energy. Work and the work-energy theorem. Conservative and nonconservative forces. Gravitational potential energy; spring potential energy. Total mechanical energy. Net work by nonconservative forces = ΔE. Conservation of energy problems. A problem in which mechanical energy is not conserved.
