Forgot all this equations nonsense. Think of your yourself living on a piece of rubber. This is very abstract but it is like a 3-D sheet of rubber. So this piece of rubber will become distorted if you place a heavy object. Now if you place another smaller object close to the heavy object it will become attracted to the smaller object. This is gravity......

Gravity on earth is 9.8 meters/second.
The masses of the objects, their distances away from each other, and whatever other gravitational forces, or maybe other forces in general, might be acting on the objects (for example, earth has a greater pull on me than my computer monitor does, so even though there's some gravity between myself and the monitor, it doesn't have any real affect).
Isaac Newton was the first scientist to define gravity mathematically when he formulated his law of universal gravitation, which says that the force of gravity between two objects (F) equals the mass of one object multiplied by the mass of the second object multiplied by the Gravitational constant (G, equal to 6.67 x 10^-11 Newton meters ^2/kg^2), all divided by the square of the distance between the two objects. This means that gravity is strongest between two very large objects, and gets much weaker as these objects get further apart.

Newtons Law of Gravitation
F(grav)= (G * m1 * m2) /(r^2)
m1 and m2 are the masses of the objects (kg)
r= distance between the centers of the objects (meters)
G = 6.673E-11
Force is in Newtons
Force is the magnitude acting on each object and is always attractive
