Calculating the speed of a pendulum at its lowest point based on its length and angle of release. In this video, I don't just solve the problem, but I also look at two possible ways of solving, and help you understand why one is better than the other. Along the way, we talk about all of the physics involved, including how we know that the forces are unbalanced when the swinging pendulum is at its lowest point.
