RVFM Centre of Gravity Apparatus

A simple and economical apparatus for demonstration of geometrical centre of gravity of two-dimensional objects.

• Uses the principle that the centre of gravity of a freely suspended two-dimensional object always lies along a line drawn vertically downward from its point of suspension
• Clear perspex rod mounted on a base with a suspension screw at the top
• 4 clear acrylic laminae – circular, triangular, square and trapezoidal
• Each lamina has suspension holes along its periphery
• The point of intersection of lines drawn from the point of suspension of 2 or more holes of a lamina gives the centre of gravity of that lamina
• Suitable for Key Stages 3 & 4 (ages 11 to 16)
