Question

In the case of a body freely falling from small height. 1.The changes of position are equal in equal intervals of time 2.The changes of velocities are equal in unequal intervals of time 3 .The changes of acceleration is zero in equal or unequal intervals of time 4.none

Answer 1

Answer:

3.The changes of acceleration is zero in equal or unequal intervals of time

Explanation:

this is because for a freey falling body acceleration is constant and is equal to g.       option 1 and 2 are wrong because in option 1 for a freely falling body

the ratio of distances travelled in successive seconds is 1:3:5.. which are not equal so option a is incorrect

in option 2 the change in velocity v-u = at here v-u is directly proportional to time so, the changes in velocities will only be equal when time interval is same so option b is also incorrect  

Answer 2
