Centre of mass
The centre of mass(or centre of
Gravity) of an object is where its
Weight is said to act from.
You can do an experiment to
find the centre of mass of a
Shape.

Turning moments

Force
A turning moment is defined
as the force applied to a beam
or lever X the perpendicular
distance from the direction of
the force to the pivot (fulcrum)
