Sia ? 4 years, 6 months ago

Centre of mass is the point at which the distribution of mass is equal in all directions and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions and it does depend on gravitational field. The centre of mass and centre of gravity are in same position if the gravitational field in which the object exists stays uniform.

Dr Pathikrt Banerjee 8 years, 4 months ago

A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods aren't available.
