What else can I help you with?
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.
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.
What is an example in which a force is exerted on an object without doing work on the object?
Pushing against a stationary wall is an example where a force is exerted on the wall, but no work is done on the wall since it does not move. Work is only done when a force causes an object to move over a distance in the direction of the force.
Why is no work done pushing on a wall?
No work is done when pushing on a wall because work is defined as force applied over a distance in the direction of the force. When pushing on a wall, the wall does not move, so there is no displacement in the direction of the force, hence no work is done.
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.

Is pushing against a wall work?
Pushing against a wall can provide some resistance and can help engage muscles in your upper body, such as your chest, shoulders, and arms. However, the effectiveness of the exercise may be limited compared to using resistance bands or weights since the wall does not offer adjustable resistance. It can still be a good way to work on your muscular endurance and strength in a pinch.
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.
Any machine which moves an object produces work.?
Not necessarily. Work is defined as the product of force and distance, so even if a machine is moving an object, it may not be doing work if the force is not acting over a distance. For example, imagine a person pushing against a wall: even though they are applying a force, the wall doesn't move so no work is done.
Is pushing a lawnmower doing work?
I think yes
Why does one get tired when pushing against a stationary wall when no work is done on the wall?
Even though no physical work is done on the wall, your muscles are still contracting and using energy to generate force. This sustained muscular effort causes fatigue and leads to a feeling of tiredness, despite the lack of movement in the wall.
Which of the following examples is NOT an example of a product of work?
An example that is NOT a product of work is maintaining a constant velocity while pushing against a stationary wall. Work is only done when a force causes a displacement, and in this case, the wall does not move even though a force is applied against it.
Explain - how you can exert a large force on an object without doing any work?
You can exert a large force on an object without doing any work by pushing against an immovable wall. In this scenario, although a large force is applied, no work is done because there is no displacement of the object in the direction of the force. Work is only done when there is both a force and displacement in the same direction.
