Answer:
In rectilinear motion F = M a describes the motion of a particle
Γ = I α (torque equals moment of inertia times angular acceleration is the equivalent law in circular motion)
A fixed central force is perpendicular to the direction of motion and cannot change the torque about the point. (for mechanical forces)
However, for electrical forces, F = Q V X B and a changing magnetic field at the center of motion can produce a force perpendicular to the direction of motion.
Perhaps, the question needs to be more specific.
