PPT-Gravity, Energy, and Light

Einstein and Newton 1 Newtonian Gravity Newton explains the universe using forces 2 Newton Newtonian gravitational theory is based on forces acting on one another An object at rest stays at rest and an object in motion stays in motion in a straight line until acted upon by another force.
