It is well known that a rain drop falls under the influence of the downward gravitational force and the opposing resistive force. The latter is known to be proportional to the speed of the drop, but is otherwise undetermined. Consider a drop of mass 1.0g falling from a height of 1.00km. It hits the ground with a speed of 50.0ms^(-1)
(a) What is the work done by the gravitational force ?

What is gravitational force?

A rain drop of mass 1.00 g falling from a height of 1 km hits the ground with a speed of 50 ms^-1 . Calculate. the gain in K.E. of the drop.

A raindrop of mass 1.00 g falling form a height of 1 km hits the ground with a speed of 50 ms^-1 . Calculate. the loss of P.E. of the drop.

What is the work done by centripetal force?/

A rain drop of mass 1.00 g falling from a height of 1 km hits the ground with a speed of 50 ms^-1 . Calculate. Is the gain in K.E. equal to loss of P.E.? If not, why?
