Question

Hello, ☺(^.^)

I have Interesting question in physics.

As we know that,
Time to reach maximum height = Time to reach back to ground
[For same body & Air resistance is neglected]

But what happened when Air is considered?

Please, Give valid reason for your Answer

Answer 1

hey mate here is your answer

whenever we leave freely any object where there is no air or can say in vaccum the acceleration is same for all objects as the gravity reamins constant throughout.

if air will be there so due to the resistance of air the rate of acceleration changes for objects as per their mass n shape n size.

in your question the case is same if the object is left freely without considering the air then the speed will be 9.8 which is the acceleration caused due to gravity.

and in second case when air resistance will be there then the rate of acceleration will increase of the mass will be more and will be reduced if the mass will. be less

Answer 2

if air resistance is considered then time to reach ground is less than the time to reach at the apex of the given height because when we are throwing an object from ground towards the top the we have to face two resisting forces first is of air and second is gravity acting in the direction opposite to the direction of motion but when we are throwing an object from top to bottom the object has to experience one resisting and one accelerating force resisting force will be provided by air due to friction but gravity will accelerate the motion with rate of 9.8 m/s as the motion is in the direction of gravity.
