Another point apart from the above two is that if the force that is F is negativa then the force acts in inwards direction and acts in outward direction in case F is positive this can be explained as F=ma and here a will be negative if it is inward as incase of a pure rolling body the V acts in the outward direction adn thus the A becomes opp of that of V and thus A becomes negative and becomes radially inward (CENTRIPETAL) & When the A is radially outward that is in the direction tangential to the V as per rotational Dyanamics than A is radially outward and thus is positive (CENTRIFUGAL)
