Question

State whether the following statements are true or false:
(a) The velocity – time graph of a particle falling freely under gravity would be a straight
line parallel to the axis.
(b) If the velocity- time graph of a particle is a straight line inclined to time axis, then
its displacement - time graph will also be a straight line?

Answer 1

since it is under constant acceleration velocity cannot be uniform. false
if vel-time graph is inclined to time axis so there is a acceleration,so displacement is also not uniform.true

Answer 2

a) false
b) true
