Скачать или смотреть Example 6.7 to 6.9 | Car Spring Collision in presence of friction | Vertical Circular Motion Problem

In this video, we will discuss NCERT solved example 6.7 to 6.9, 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 if we don't know the force expression. otherwise if we know the expression we can use work done definition.
Here we will discuss vertical circular motion in detail with the help of conservation of mechanical energy and work energy theorem. To test the car crash situation we will consider car collision with spring with and without friction force on the surface.
