Centripetal Force and centrifugal force
Have you ever seen a helicopters blades move round and round in a circle? The blades move in a circle and that is how the helicopter flies. But did you know that the helicopter would not be able to fly with out something called centripetal force. What is centripetal force? Centripetal force is when something moves is a circle and move to the center. Centripetal force happens every time something spins in a circle! Even when your parents turn in a car! But there also is something called centrifugal force this is the oppiset of centripetal force, by having something moving in a circle away from the center. If centripetal force and centrifugal force were not here to balance each other turning/ moving in a circle would be a lot harder.
