  • Centrifugal force

    When something is going straight, it always keeps going straight unless something else stops it or turns it. If it can’t go straight, then it goes as straight as it can. So when you hit a ball tied to a rope, it tries to go straight away from you. But the rope pulls on it and keeps the ball from going straight. So the ball goes as straight as it can – around the pole in a circle. That’s centrifugal force – the energy of something trying to go straight even though it can’t.

    The Earth is affected by centrifugal force. It is moving, so it tries to keep moving in a straight line. But the gravity of the Sun pulls the Earth toward it, just as the rope pulls the ball. Gravity can’t pull the Earth into the Sun, because the Earth keeps trying to go straight. So the Earth takes a middle road, going in a circle around the Sun.

    Following is a video about centrifugal force.
