Скачать или смотреть Exercise 6.13 to 6.14 | Work Done on Rain drop under air resistance during free fall | 2d Collision

In this video, we will discuss NCERT unsolved exercise Problem 6.13 to 6.14, mainly the problems are related to work done calculation. Work energy theorem can be used to find work done by conservative as well as nonconservative forces or resistive force if we don't know the force expression. otherwise if we know the expression we can use work done definition.
Here we will calculate work done on Rain drop under air resistance during free fall for gravitational and resistive force. We also discuss problem related to 2d elastic collision.
