Lecture 16 - Circular Motion
... Here we have an object moving in a circle with a constant speed. Why is there any acceleration? Simply because velocity is a vector quantity, and in this case, its magnitude doesn’t change, but its direction does. Consider our moving object at two times: It has moved from r zero to r. Here I have mo ...
