Question
Why does Newton’s first law of motion appear to be contradicted in our day-to-day life?
Solution
In our daily practical life, we have observed that when we apply external force on a moving body, it covers some distance before it stops. This is in contradiction to Newton’s first law.
However, the motion of the body is being opposed by force of friction between the body and the ground and also by air resistance. In the absence of such forces, the body would continue to move on its own.
