Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. They also analyze why all forces on an object must cancel out exactly for an object to be stationary.

Determine the unknown mass that is being balanced by two known masses for a meter stick balanced at its center of mass (50.0 cm mark).
