CENTER OF GRAVITY
Center of Gravity• the point at which all the weight of an
object maybe considered to be concentrated
• point at which the object may be supported and balanced (when the only force acting on object is gravity)
• center of balance (stability)
• may be outside the object
• c.g. or c.o.g.
C.o.g. of uniform or regular shaped object is at the geometric center of the object
C.o.g. of irregular shaped object is determined by:
1. suspension method
the object is suspended by any means and is allowed to come to equilibrium
2. Mathematical Method
1.
2. A meter stick weighs 200 grams.
Three masses of 100, 200, 150 grams
are placed at the 10-cm, 20-cm, and
60-cm points, respectively, of the
meter stick. Where is the center of
gravity of the system?
Seatwork ½ cross.
