Hi there, New to the forums, but have been periodically browsing posts as a guest. Anyways, I'm having trouble understanding and solving circular motion problems, but not finding angular velocities and what not, more so with respect to Newton's laws (forces). Such problems like uniform and non-uniform circular motion. Is there a website that I could be directed to to learn more about these types of problems or possible advice from one of the members? I understand how circular motion problems work, but I don't get how to set them up. My professor said something of summing the forces in the Z-direction and in the radial direction. I want to have some basic understanding of what he was saying before seeing him.
