Ok let's say there is a pendulum and you start 45 degrees from the left and let go. I understand the farthest down point on the circle has the greatest velocity, but I don't understand why there is no tangential acceleration. Any help?
From http://en.wikipedia.org/wiki/Tension_(mechanics)" [Broken]]:I don't understand that because I have not learned about force or tension yet.
tension is the magnitude of the pulling force exerted by a string, cable, chain, or similar object on another object. It is the opposite of compression
