The world needs a new source of energy, an unspillable source.

5. The Electric Potential and Conservation of Energy

Fundamentals of Physics, II (PHYS 201) The law of conservation of energy is reviewed using examples drawn from Newtonian mechanics. The work-energy theorem is derived from first principles and used to initiate a discussion of the vector calculus underlying the law of conservation of energy.
