Obviously 20 N of force, right? Since neither object goes anywhere.
-- no work is done, in the Physics sense
-- the reaction force of the wall pushing against the student is 20 N
there can be force without movement. an example of this would be when a person pushes against a wall :)
poo works. ;)
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.
Friction.
you push on the wall and the wall pushes back on you with opposite and equal force.
what force pushes a cell membrane against a cell wall
'Thrust' pushes against it from the rear, and 'drag' pushes against it from the front.

Air Resistance is a force that pushes up against gravity.
poo works. ;)
It works when a resisting force pushes against it and it then moves back into its original position.
Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.
