Acceleration Characteristics for Circular Motion
... In that case, you treat this case the same way you did in any dynamics problem, the sum of the forces matters...not any one force. So for instance, if we changed the prior example by having the object moving in a vertical circle, rather than a horizontal one, we have two forces acting on the object ...

When lowering an object, the force you apply to support it (and keep it from dropping too fast) is NOT in the same direction as its motion. In fact it is OPPOSITE. Instead we think in terms of ...
