Question

A ball is thrown in vertically upward direction. Neglecting the air resistance, acceleration of a ball in air will be ................
(A) zero
(B) continuously increasing
(C) remain constant
(D) increase when ball is going up and will decrease when it is coming down.​

Answer 1

since air resistance is taken into account, the acceleration due to gravity as it goes up also decreases. Hence g will be less at the highest point.
