Friction.
Kinetic motion as the chair moves. Also overcoming the static friction of a stationary chair, and the kinetic friction between the sliding chair and the floor (which is created by the force of gravity and the interaction of the floor surface with the bottoms of the chair legs).
Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.

A push or pull that acts on an object is a force.

That's a trick question, right? Jupiter has no surface.
