## Passage

Pseudo force is an imaginary force which is recognized only by a non-inertial observer to explain the physical situation according to newton’s laws. Magnitude of pseudo force F is equal to the product of the mass m of the object and the acceleration a of the frame of reference. The direction of the force is opposite to the direction of acceleration, F =-ma
