Force, inertia and linear momentum

Force: The pull or push which change or tends to change the state of rest or of uniform motion or direction of motion of an object is called Force.

The units and dimension of force:


We know that                                  F = ma

There are two types of units of force

(i) Absolute Units:

(a) In M.K.S or S.I unit, the absolute unit of force is Newton (N)

Where                                                    1N = 1kg ´ 1m/s2

So 1N is the force which produces an acceleration of 1m/s2 in a body of mass 1 kg. Continue reading “Force, inertia and linear momentum”
