The center of gravity of a collection of masses is the point where all the weight of the object can be considered to be concentrated. If (xcg,ycg) are the coordinates of the centre of gravity of a collection of point masses m1 , m2 , etc, located at coordinates ( x1,y1 ), ( x2,y2 ), respectively, then:
(m1 + m2 + ..)gxcg = m1gx1 + m2gx2 +... (5)
(m1 + m2 + ..)gycg = m1gy1 + m2gy2 +...

the center of gravity is simply the point where the gravitational forces are equal, the simplest example is a teeter totter. if the person on each side weight the same amount then the center or gravity is right in the middle. if one of the people is heavier then the center of gravity would be closer to the heavier person.

a center of gravity is a point on an object that is basically the center of mass. for example on a baseball bat. the center of gravity is nearer to the top because there is less mass on the bottom. when you throw it, the bat will spin around its center of gravity.
