What is pushing against a brick wall an example of?
Pushing against a brick wall is an example of a futile or pointless effort because the wall is unlikely to move or be affected by the force applied to it.
Why do your arms raise after pushing against a wall?
When you push against a wall, your muscles contract to exert force. Once you stop pushing, your muscles relax. The relaxation of these muscles causes your arms to rise due to the opposing forces of gravity and the initial force exerted against the wall.
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.
If you were pushing very hard against a brick wall would you be doing work?
Yes, pushing against a brick wall would require force and displacement, which are the two components of work. You would be exerting energy to apply a force on the wall, but if the wall doesn't move, there would be no work done on the wall.
What is the reaction force to someone pushing against a wall?
The reaction force to someone pushing against a wall is equal in magnitude but opposite in direction to the force they are applying on the wall. This is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

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?
The force is typically due to the muscles in your fingers contracting and exerting a pushing force against the wall, resulting in your fingers bending. This force is a result of the interaction between your muscles and the wall, known as the normal force.
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.
Is pushing up against a wall doing work?
Physically pushing against a wall can be considered as doing work in a physics context, as work is defined as the force applied over a distance. The force you exert on the wall does not result in any displacement of the wall, but work is still being done in the physics sense, as long as the force is being applied.
Example pushing on a wall?
When you push on a wall, the wall exerts an equal and opposite force back on you, as described by Newton's third law of motion. This is due to the interaction between the force you apply to the wall and the reaction force the wall applies to you. As a result, you may feel the resistance of the wall pushing back against you.
Is any work done by pushing wall?
No, pushing against a wall does not result in any work being done. Work is only done when a force causes an object to move in the direction of the force, so if the wall does not move, no work is done.
You hit a wall with a stick the equal but opposite reaction is the wall push against you the stick pushes against you you push against the stick or the wall pushes against the stick?
The equal and opposite reaction is the wall pushing back against you. When you hit the wall with a stick, the force you exert on the wall is transferred to you through the stick, causing the wall to push back with an equal force. The stick simply transmits this force between you and the wall.
