When a character jumps, is a force applied on the ground or the object player is standing on?

Is a force/impulse applied on the ground when a character jumps? I know when a character lands on something, an impulse is applied on the ground.
For example - When a character/pawn is jumping/landing on a physics simulated object.
As far as i tested, a force is not applied on the jumping from object. Is there an option to add, or do we have to add manually using Line traces and add_Impulse function.
