18 Is it possible for an object moving with a constant speed to accelerate? OA No, if the speed is constant then the acceleration is equal to zero. B No, an object can accelerate only if there is a net force acting on it. OC Yes, although the speed is constant, the direction of the velocity can be changing. OD Yes, if an object is moving it can experience acceleration OE I need help
