Centrifugal force is a pseudo force. So is gravity. They do exist, and are needed to get correct answers when working in a non inertial frame of reference. | |

Inertia: your body is trying to continue going in a straight line, centrifugal force: the friction between the wheels of the care and ground acts as a centripetal force on the car. | |

| Nov 10, 2010 at 17:36 | comment | added | Adrian Mester | I think centrifugal force is correct. The object's inertia "tries" to keep the object moving in a straight line, the same thing that happens when you swing a rock tied to a rope. | |
| Nov 10, 2010 at 17:08 | comment | added | Cedric H. | This is a very misleading answer: there is no "centrifugal force", just a centrifugal pseudo-force in a rotating frame. When you look at a bike you generally do not consider a rotating frame, and even if you do, how would you relate the rotational speed of the frame, leading to a centrifugal term to the speed of the bike ? | |
