Question

different between real force and pseudo force​

Answer 1

Answer:

Real Forces are considered to have a real existence and the Newton's laws can successfully account for them. ... In physics, pseudo forces arise when Newton's laws of motion are applied in a non-inertial (accelerating) frame of reference

hope this will help u

Answer 2

Answer:

The main distinction is that a real force is cognizant even in an inertial frame while a pseudo force is only apparent in a non-inertial or accelerating frame.

Case in point is an elevator moving up with the acceleration g in empty space. Now consider yourself in that elevator. If you now release a ball in that elevator, the ball, if not in contact with the elevator, would simply keep floating. This is what an inertial observer outside the elevator in the empty space would see. That observer would conclude that there is no force on the ball. But the observer would note that the upwards accelerating elevator floor would soon hit the free ball.

However, in your view which is from the inside of the elevator, the ball would seem to fall to the floor of the elevator. So for you, it would be as if there is a downward force with acceleration g on the ball, even though it is the elevator floor which is rushing towards the ball. This is the pseudo force, which is a perfectly valid observation in an accelerating/non-inertial frame.

Replace the elevator with a merry-go round and you get the centrifugal force which is the pseudo force.
