Question

According to V=(2gh)1/2,an object falling from a great height should have a very high velocity. That means a raindrop and a hailstone should hit the ground very hard with a terrible speed.But why doesnt that happen?

Hi Chilukuri Kartik That relation V=(2gh)1/2 is drive for ideal case. in derivation of this formula we have not consider the effect of drag forces. Drag force acts in the reverse direction of the movieng particle.the more the velocity the more will be drag force.so it reduce the velocity of moving particle.. Thats why a raindrop and a hailstone should not hit the ground very hard Please feel free to post as many doubts on our discussion forum as you can. If you find any question Difficult to understand - post it here and we will get you the answer and detailed solution very quickly. We are all IITians and here to help you in your IIT JEE preparation.

According to V=(2gh)^1/2,an object falling from a great height should have a very high velocity.

That means a raindrop and a hailstone should hit the ground very hard with a terrible speed.But why doesnt that happen?
