An object's gravitational force (its weight) acts through a point called its centre of gravity.
The centre of gravity acts at the same point as the centre of mass.
The centre of mass is a point where an object's weight appears to act.
A freely suspended object will come to rest with its centre of gravity vertically below the point of suspension.
You can use a plumb line to find the centre of gravity.
A small hole is made at the edge of the object. The object is suspended by a pin. A plumb line is hung from the same pin and a line drawn along the vertical string of the plumb line.
The procedure is repeated twice. The centre of mass is the point of intersection of the three lines.
