In physics, a pseudo force is a force that appears to act on a mass but is actually due to the acceleration of the frame of reference in which the mass is situated. It's not a real force caused by an interaction but is introduced to account for the effects observed in a non-inertial reference frame, where Newton's laws of motion might not hold directly. Common real-world examples include the centrifugal force experienced in a rotating frame of reference and the Coriolis force due to the rotation of the Earth. Pseudo-forces are essential for describing motion accurately in accelerated or rotating systems.
This video highlights how Newton's second law leads to different values of tension for different frames of reference, thus illustrating the importance of applying a pseudo force in a non-inertial frame of reference.
