Centripetal Acceleration & Force Objects in circular motion are accelerating towards the centre of the circle. How is this possible if they are going at constant speed? If the objects are being accelerated, then they are being acted upon by an unbalanced force (the Centripetal Force) which acts towards the centre of the circle. How would this force vary with the 1) mass of the object, 2) radius of the circle, 3) speed?

What provides the centripetal force?

Car cornering?
