Required Answer
Frictional force:
The force that opposes the motion of the moving objects is called frictional force.e.g to walk or to run friction is needed to push the ground backwards.
pressure:
The force acting normally per unit area on the surface of the body. e.g A drawing pin with a sharp tip enters easily when pressed on a woooden board.
One kilogram force:
One newton (1 N) is the force that produces an acceleration of 1 m/s² in a body of mass of 1 kg.
1N = 1kgm/s²
