Hi guys,
supposing there is a collar which can freely move along a rod. If the rod is rotating with a certain angular velocity, the rod will move away from the rotating point (it can never move towards the point). The acceleration of the collar has a radial component toward the point, hence the radial force acting on the collar has a direction toward the rotating point.
My question is why are their directions towards the point while the motion of the collar is out??
when I pull a box, the box's acceleration will have the same direction as the my pulling force and so does its motion. What makes the collar analysis different?
Thnx
