The natural laws of rotation have the same direction if left to itself.


An object is said to be in unform circular motion when it travels in a circle at a constant speed. Although the speed is constant, the velocity continually changes as the direction changes. Hence, this motion is described as an accelerated motion and this acceleration tends to be directed toward the center. Why is this so when the centrifugal force seems to be directed outwards? This effect is caused by the change in the direction of the tangential velocity of the body in motion. In order for the direction of a body's motion to be changed, an external or internal force must be applied. Hence, the greater the change of the angle, the greater centrifugal force will be experienced. On the contrary, if the object's final tangential velocity about a center is less than the initial velocity, then the object will experience a deceleration.

Imagine being in a car and driving at a constant speed. Both your body and the car are in motion together. If you step on the brake, you will experience a force that pushes you forward. Actually, it wasn't really a force since there was no acceleration. It was the natural state of your motion that causes your to move forward while the car is slowing down. Relatively, speaking, the deceleration of the causes an equal acceleration on you and therefor, you felt a force. Likewise, while the car turns around a bend, your natural state of motion is straight while the car is angiualr and therefore, centrifugal force is "created".
