Euler force In classical mechanics, the Euler force is the fictitious tangential force that is felt in reaction to any angular acceleration. That reactive acceleration is the Euler acceleration (named for Leonhard Euler), also known as azimuthal acceleration or transverse acceleration. In other words, it is an acceleration that appears when a non-uniformly rotating reference frame is used for analysis of motion and there is variation in the angular velocity of the reference frame's axes. This article is restricted to a frame of reference that rotates about a fixed axis. The Euler force is related to the Euler acceleration by F = ''m''a, where a is the Euler acceleration and ''m'' is the mass of the body. == Intuitive example ==
The Euler force will be felt by a person riding a merry-go-round. As the ride starts, the Euler force will be the apparent force pushing the person to the back of the horse, and as the ride comes to a stop, it will be the apparent force pushing the person towards the front of the horse. The Euler force is perpendicular to the centrifugal force and is in the plane of rotation.
