Homework Statement
Hello. I was just wondering. You have a simple pendulum . string and a ball with mass at the end. We usually solve examples and we think about conversation of kinetic energy and potentional energy. I was just wandering if there is also something like vertical kinetic energy. Or it is just a part of kinetic energy itself (just the sine part of velocity vector). If it exist, i know it is very small. I was just wondering... Thank you.
