What is a fictitious force?

Question:

What is a fictitious force?

Frame of Reference

From the field of mechanics, motion like no other is said to be relative. With this, a frame of reference is established for the observation of physical phenomena or event. This is a combination of a particle's reference point coupled to a set of directions.

Answer and Explanation:

A fictitious force is a non-inertial type of force which acts on object viewed by an observer resting or residing in an accelerating frame of reference. This is different from the usual forces that one deals in mechanics. Fictitious forces also occur when the frame of reference is rotating. Take a moving car for instance, when a person sitting in this moving car views a stationary object, he finds that the object is accelerating with respect to the car.
