Centrifugal force

In Newtonian mechanics, a centrifugal force is a kind of fictitious force that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed perpendicularly fro

Riders on a swing carousel interpret the cessation of upward motion as a balancing of the force of gravity, the force of the tension of the chains, and a centrifugal force pushing them away from the center of rotation. A stationary observer on the ground observes uniform circular motion, which requires a net centripetal force that is the combination of the force of gravity and the force of the tension of the chains.
The interface of two immiscible liquids rotating around a vertical axis is an upward-opening circular paraboloid.

Coriolis force

In physics, the Coriolis force is a pseudo-force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation
Centrifugal force
…merry-go-round or vehicle, this is much more well-known than centripetal force. Motion relative to a rotating frame results in another fictitious force: the Coriolis force. If the rate of rotation of the frame changes, a third fictitious force (the Euler force) is required. These fictitious forces are necessary for the…

Image from Cursus seu Mundus Mathematicus (1674) of C.F.M. Dechales, showing how a ball should fall from a tower on a rotating Earth. The ball is released from F. The top of the tower moves faster than its base, so while the ball falls, the base of the tower moves to I, but the ball, which has the eastward speed of the tower's top, outruns the tower's base and lands further to the east at L.
