trivial centripetal force..... hello forum, a simple, qualitative question. A centripetal force serves to curve the trajectory of an object (acceleration that only changes the velocity direction, not the magnitude). But why is the object not pulled inward as well? I can see the turning but not the fact that the obj stays at a constant distance from the pivot. If the object was a rest, a force towards the center would drag it there. But if the obj rotates, it doesn't. For the fact that it has speed. Is it maybe always trying to "escape" in the straight line, so the distance that it would be pulled in is matched by a distance traveled radially out? thanks!
