Centripetal force and acceleration?
Yes, there is centrifugal force. To explain, an object traveling in a circle, like a test tube in a centrifuge, will want to travel in a straight line, instead of a circle. So centrifugal force els the object away from the center of rotation.A good example of this would be the orbit of a planet. Gravity acts as centripetal force, pulling the planet towards the star, and without centrifugal force, the planet would be pulled into the star. But if there were only centrifugal force, no gravity, that planet would be flung in a straight line.For a centrifuge, the centripetal force is the centrifuge itself. Without it, the test tubes would be flung against the wall. There is no centripetal force inside the test tube, so the contents are flung away from the center of rotation.
