SUMMARY

An object cannot move in a circular path without experiencing acceleration. According to Newton's 1st and 2nd Laws, a net force of zero results in straight-line motion. Therefore, for an object to maintain a circular trajectory, it must be subjected to a centripetal force, which inherently involves acceleration. This conclusion is definitive and aligns with classical mechanics principles.

Under no circumstances. No acceleration means a net force of zero. Newton's 1st and 2nd Laws say that a particle not acted on by forces will move in a straight line.
