When an observer is in an accelerating frame, then the observer has to apply an extra force F vectors on any particle, besides the real forces acting on the particle to draw the free body diagram of the body with respect to him. This F is called PSEUDO FORCE. This is exerted to apply Newton’s laws on the particle, because it is not applicable w.r.t. an accelerating frame. F ma, where m is the mass of the body and a is the acceleration of the observer. Negative sign shows that direction of F ’is opposite to the a An observer is standing inside a trolley and observing a block inside the trolley as shown in the figure Mass of the block is m.
