Apparent (Fictitious) Forces

Apparent or fictitious forces are derived by extending the second Newton's law to non-inertial reference frames. Non-inertial reference frames are those that are accelerating (e.g., rotating coordinate systems), whereas the inertial coordinate systems are either at rest or moving with a constant, uniform velocity. We first derive the general expression for apparent forces and then apply that expression to the special case of rotating reference frames. As a result, we obtain expressions for Coriolis force, centrifugal force, and Euler force. However, the Euler force disappears under the assumption of the constant angular velocity of the system.
