Physics (NTSE/Olympiad)  

1. Motion

Body Falling Freely Under Gravity

Assuming u = 0 for a freely falling body :

Body is projected vertically up :
Taking initial position as origin and direction of motion (i.e. vertically up) as positive.
(a) At the highest point v = 0
(b) a = – g

It is clear that in case of motion under gravity
(a) Time taken to go up is equal to the time taken to fall down through the same distance.
(b) The speed with which a body is projected up is equal to the speed with which it comes back to the point of projection.
(c) The body returns to the starting point with the same speed with which it was thrown.
