It is advised that you watch the previous three lectures to fully understand this one : Work energy power Lecture 1 https://www.youtube.com/watch?v=xqPdwx9NFg4 Work energy power Lecture 2 https://www.youtube.com/watch?v=1bRRCS46amc Work energy power Lecture 3 https://www.youtube.com/watch?v=EcGyIeDhKbg Work energy theorem for a system of particles and related solved problems. May be watched by every Physics-studying student. It is advised that you should pause the lecture and attempt solving the problem at least two-three times and only then resume it again to see the solution and then again analyse what was wrong with his\her approach. If you couldn't figure out the reason then probably you haven't understood the concept. It is equally important to be familiar with the "incorrect approaches" to a problem. In the next lecture, we shall deal with conservative and non-conservative forces.
