Also known as pseudo force, d'Alembert force, inertial force, fictitious forces, pseudo forces, inertial forces
apparent force that acts on all masses whose motion is described using a non-inertial frame of reference, such as a rotating reference frame
The Coriolis force is an example of a fictitious force. The camera on the right is rotating, so it represents a non-inertial reference frame. This is why the marble seems to be moved by a force.
A fictitious force, also known as an inertial force or pseudo-force, is a force that appears to act on an object when its motion is described or experienced from a non-inertial frame of reference. Unlike real forces, which result from physical interactions between objects, fictitious forces occur due to the acceleration of the observer's frame of reference rather than any actual force acting on a body. These forces are necessary for describing motion correctly within an accelerating frame, ensuring that Newton's second law of motion remains applicable.
