Question

what is pseudo force give an example

Answer 1

When a bus suddenly begins to accelerate , the person inside the bus feels that he is pushed backward into the seat . There is no real force pushing him back . This force is pseudo force .

When a bus suddenly begins to decelerate ( to stop ) the person inside the bus fells a that he is pushed forward . There is no real force pushing him to the front . This force is pseudo force .

When a bus suddenly turns left , the person inside the bus feels he is pushed toward right . There is no real force pushing him to the right . This force is pseudo force .

When a bus suddenly turns right , the person inside the bus feels he is pushed toward left .There is no real force pushing him to the left . This force is pseudo force .

When a lift suddenly falls down with an acceleration , person inside the lift feels an upward force acts on him . There is no real force pushing him up . This force is pseudo force .

When a lift suddenly moves up with an acceleration , person inside the lift feels as if he is pushed down with some force . There is no real force pushing him down . This force is pseudo force .

The Coriolis force is a pseudo force .

It acts on objects that are in motion relative to a rotating frame of reference . In a reference frame with clockwise rotation, the force acts to the left of the motion of the object. In one with anticlockwise rotation, the force acts to the right.

Answer 2

A physically apparent but nonexistent force felt by an observer in a noninertial frame (that is, a frame undergoing acceleration). Newton's laws of motion hold true within such a reference frame only if the existence of such a force is presumed. The centrifugalforce is an example of apseudo force.
