Is pushing up against a wall doing work?
No,beacuse the wall is oushing against you. For work to be done, it has to be done in the same direction.
What are the forces act on a retaining wall?
Outward Force: dirt pushing against retaining wallInward Force: atmospheric pressure, the retaining wall pushing against the dirtDownward Force: gravity, atmospheric pressure, the retaining wall pushing against the earth.Upward Force: The earth pushing against the retaining wall.
What will be the reaction if the action is you leaning on a wall?
The reaction is the wall pushing back on you.
Can you lean against a wall if frictional forces are absent?
you can lean against a wall because it's pushing back
Why doesn't a wall move when you push it?
The pushing force exerted by physical human effort against the wall is not enough! If the pushing force becomes greater than the weight of the wall held down by the earth's gravity, then the wall will topple. A mechanical digger is able to exert a greater side force then a human, and will topple (demolish) the wall.

Why do you feel exhausted after pushing a wall?
Beacause u cant move the wall
Why the displacement is zero when a man is pushing a wall?
This is because the wall is firmly rooted to the ground.
What will be the reaction if the action is you leaning on a wall?
The reaction is the wall pushing back on you.
What is he definition of work?
Work is the product of a force and the distance through which it acts in the direction of the force. In order for work to be done, the object must move in the direction of the force. If you push on a brick wall until you exhaust yourself and the wall doesn't move, you have not done any work. If you push on a box and it moves in the direction that you are pushing it, you have done work.
How do you brake the wall in Astro Knights poptropica?

What kind of force would pushing on a wall but it not moving be?

How do you make a simple electric bulb go out?
Usually it is by pushing the switch on the wall into the down position. If that does not work, turn the bulb until it does not make contact and fix the switch.

A student pushes against a wall with 20 N of force and the wall does not move In this situation?
Obviously 20 N of force, right? Since neither object goes anywhere.
