Problem
A small object is released from rest at the edge of a high platform. Take the downward direction as positive.
(i) Define uniform acceleration.
(ii) With the stated sign convention, write the expressions for the object’s velocity and displacement after an arbitrary time t.
(iii) Using a velocity–time graph, explain why the displacement varies as t2 for such motion.
