Question

What type of motion ,uniform or non uniform is exhibited by a free falling body? give reason for your answer?

Answer 1

The motion of a free falling body is a non-uniform as the free falling body covers smaller distances in initial '1 second' intervals and larger didtancein later '1 second'. This happens due to the gravitational force. As per the rule of gravity every body falling freely from a hight will certainly be attracted towards the earths surface. Therefire as the free falling body falls from a hight the earths gravity attracts it towards the earths surface. And the distance is changing according to time because as the free falling body nearers to the earth surface the force of gravity upon it increases.

For eg. If we drop a ball from roof top building we find that it covers a distance of:

4.9 m in the 1st sec
14.7 m in the 2nd sec
24.5 m in the 3rd sec and so on.
