Force
What is force?
According to newton, force is something which changes the state of motion
of the object. If we want to make a stationary object move, we have to
apply forces. If we want to make a moving object move faster or slower
, again we have to apply forces.
We can use a newton balance to measure forces. The unit of force is the
Newton (N).
