Since the acceleration of the object moving in a circle is always towards the center of the circle, the net integral of the acceleration will be nearly zero. Wow. Why am I going through all this? THe obvious thing is that velocity is a VECTOR. Thus the object whirlig in a circle may have a lot of SPEED, but not much velocity when averaged over time. If I am not mistaken, relativistic effects depend on velocity, not on speed. GREG ucbvax!hplabs!hao!woods menlo70!hao!woods harpo!seismo!hao!woods decvax!brl-bmd!hao!woods
