12.2. Equilibrium 2 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 Equilibrium: P = const . linear momentum of center of mass (COM) is constant L = const . angular momentum about any point is constant Static equilibrium: P = 0 linear momentum of COM is zero L = 0 angular momentum about any point is zero

12.4. The Center of Gravity 5 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 If g is same for all parts of the body then its center of gravity (COG) is same as its center of mass (COM) A single point exist in the body where sum of all gravitational forces of its parts act. This point is called center of gravity of the body.
