Force= mass x acceleration (The Second Law of Motion)
the force of gravity on an object
Weight= mass x acceleration caused by gravity
symbol representing the acceleration caused by gravity; 22 mph/s, 32 ft/s/s, or 9.8 m/s/s
The Law of Gravity
F= GmM/d^2; discribes the strenght of the force of gravity between two objects of mass "M" and "m" separated between their centers by the distance "d"
General Theory of Relativity
explains the relationship between the geometry of space and the flow of time in our Universe
