Why does Newton's first law of motion appear to be contradicted in our day-to-day life?

Answer:

                In our day-to-day observations, we find that when we push a block lying on the surface of a table, it covers some distance before it stops. At first sight, it seems to contradict Newton's first law of motion. However, the motion of the block is being opposed by the force of friction between the block and the table and also by air resistance. In the absence of such opposing forces, the block would continue to move on its own.
