The centripetal acceleration is the same whether the object moves clockwise or counter-clockwise. Centripetal acceleration is the result of the sum of other forces. Quiz Information O If an object is moving at a constant speed in a circle, then every external force must point towards the center of the circle. If the speed of an object is constant, then its acceleration must be zero. If the speed of an object is constant, then its acceleration must be zero.
