Is pushing on a wall work?
Pushing on a wall does not result in work being done in the physics sense, as work requires displacement of an object in the direction of the force. The wall does not move, so no work is done on it. However, your muscles are still expending energy to push on the wall.
If you push for an hour against a stationary wall you do no work why?
Work is calculated as force multiplied by displacement in the direction of the force. In this scenario, since the wall doesn't move, there is no displacement in the direction of the force. Therefore, no work is done on the wall.
How possible for a force to act for a long time and yet does no work?
For example : when we push a wall it doesn't move anywhere I think you don't know the equation for work Work =force* distance For something to work it should move too then there is no work done In the example we push the wall yet it doesn't move to a distance So no work done
What muscle push hard against the wall?
muscle that push hard to wall
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.
You and your friend push against a wall What if your friend stops after 10 min while you push for 5 min longer Compare the work you and your friend do?
0 neither of you have done any work
According to Newton's third law of motion, if you push against a wall, the wall will push back with an equal and opposite force. What will the wall do in response to your push?
According to Newton's third law, the wall will push back against you with an equal force in the opposite direction.
Is painting a wall push or pull?
It's a push
If you stand next to a wall on a frictionless skateboard and push the wall with a force of 40 N how hard does the wall push on you?
The wall will push back on you with a force of 40 N, according to Newton's third law of motion.
What happens when you push off from the wall?
Presuming the wall to be the canonical wall in a home, vertical, static, and nominally constructed; pushing off the wall would have the effect of increasing your distance from it. Your muscles perform work on the mass of your body, accelerating it and hence transferring energy to it, increasing your momentum and kinetic energy.
What is an example of an action the does no work?
An example of an action that does no work would be pushing on a stationary wall. Despite applying force to the wall, since the wall does not move, no work is done as defined in physics (work = force applied * distance moved in the direction of the force).
If you push for an hour against a stationary wall you do no work?
That's correct. Work is only done when a force causes an object to move in the direction of the force, so pushing against a stationary object, like a wall, does not result in any work being done.
