Let there be an obj. which is made to fall from a certain height in a gravitaitonal field. where a= 10 metre per second squared Say it falls for 1 second. v(final velocity)= 10 metre per second. How much distance does it cover in that 1 second? distance = speed x time = avg. speed x 1second = 10 m This means that 10 m is covered during that 1 second. But how could that be when the velocity had not reached 10 metre per second?
