- In a vacuum, acceleration due to gravity is constant for all objects ($g$). - Absence of air resistance. - Time taken to fall from the same height is independent of mass.
In a vacuum, a five-rupee coin, a feather of a sparrow bird and a mango are dropped simultaneously from the same height. The time taken by them to reach the bottom is t1, t2 and t3 respectively. In this situation, we will observe that
