Fictitious forces

These are apparent forces that object experience in an accelerating coordinate system like an accelerating car, airplane, spaceship, elevator, or amusement park ride. Fictitious forces do not arise from an external object like genuine forces do, but rather as a consequence of trying to keep up with an accelerating environment.

• Centrifugal force – The force experienced by all objects in a rotating coordinate system that seems to pull them away from the center of rotation.
• Coriolis force – The force experienced by moving objects in a rotating coordinate system that seems to deflect them at right angles to their direction of motion.
• “G-Force” – Not really a force (or even a fictitious force) but rather an apparent gravity-like sensation experienced by objects in an accelerating coordinate system.
