Re: Pendulum acceleration



In other words, the NET FORCE, and thus the acceleration, is
zero at the bottom and non-zero at an angle, large or small.

How can this be? Clearly it is moving the fastest at the
bottom and an instant later it must be moving slower.
This is a change in velocity - this is an acceleration. To
have an acceleration, a force must be present. Or am I
completely wrong of my understanding of motion?
