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.
Can you lean against a wall if frictional forces are absent?
you can lean against a wall because it's pushing back
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 will be the reaction if the action is you leaning on a wall?
The reaction is the wall pushing back on you.
When you push against a wall with your fingers they bend because they experience a force. What is this force?
It is the force of the wall pushing against your fingers. This is related to Newton's Third Law.

The reaction is the wall pushing back on you.
How do you show that for every action there is an equal and opposite reaction force?
when you push your hand against a wall the wall is 'pushing' against you that is why you feel your hand being pushed.
When you push against a wall with your fingers they bend because they experience a force. What is this force?
It is the force of the wall pushing against your fingers. This is related to Newton's Third Law.
Which muscle is used when pushing against a wall?
it depends on from what direction and what angle. and what part of you body that you are using.
How to calculate the normal force acting on an object held against a wall given mass and force?
Force of horizontal normal to the wall reaction on the object will be exactly equal to the force you're pushing it against the wall with.
What is pressure produced by water pushing outward against the cell wall of plant cells?
Turgor pressure
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.
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.
What muscles are involved in pushing hard against a wall?
Protraction of the scapula, produced by actions of both the serratus anterior and pectoralis minor muscles.
