Tho masses, m1 and m2, and separated by a distance, d12 , are subjected to and attractive
gravitational force, FG , given by :
FG = ( KG ) ( m1 ) ( m2 ) / ( d12 )^2
KG = gravitational constant
KG = 6.672 x 10^-11 N - m^2 / kg^2
Gravity
Centripetal ("towards the center") force is a real force, that pulls something towards the center during a circular movement. Centrifugal ("center-fleeing") force is a ficticious force, required to explain the observed reactions in a rotating frame of reference.
the force of gravity
ma granny (:
gravity
Gravity pulls objects towards each other.
A centripetal force is a force that pulls something, that is moving in a circle, towards the center - in other words, keeping it in circular motion.

Gravitational force (or gravity) is a force that pulls things together.
