1) When you push an object on a flat surface work is being done against the force of friction (and air resistance). Work is calculated by the formula:
Work = Force applied x distance moved in the direction of the force
2) When you push a spring to compress it, you are doing work against its stiffness
In this case, Work = Force applied x 0.5 x decrease in length of spring
3) When you push something vertically upwards, you are working against gravity
Here, Work = mass x earth's gravity x height raised
What else can I help you with?
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.
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.
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.
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.
Is pushing against an immovable object is an example of work?
when force is applied and work is done In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. for example if u climb a tree u are doing work and force is applied
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.
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
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.

What type of work is done when being a doctor?
it varies from each profession

What type of work is being done when pulling?
Pulling is a type of physical work where force is applied to move an object towards oneself or to draw something closer. It requires muscular effort to overcome resistance or friction. Examples include pulling a rope, opening a door, or dragging an object.
In what activities are you doing work in its scientific meaning A sitting still on a rock B pushing against a rock but not moving it C pushing the rock over a cliff?
In activity B, where you are pushing against a rock but not moving it, work is being done in its scientific meaning as the force you apply results in a displacement over time, even though the rock doesn't move. In activities A and C, no work is being done because there is either no displacement in the case of sitting still on a rock (A) or no force causing a displacement in the case of pushing a rock over a cliff (C).
The illustration shows Beatrice pushing on a heavy box Beatrice pushes with a force of 40 N How can you determine if Beatrice is doing work on the box?
To determine if Beatrice is doing work on the box, we need to know the distance over which she is pushing and the direction of the force she is applying. Work is done when a force is applied in the direction of motion over a distance. If Beatrice is pushing the box in the direction of motion over a distance, then work is being done on the box.
What happens to the temperature when work is done on the system by pushing it?
When work is done on a system by pushing it, the internal energy of the system increases, leading to an increase in temperature. The work done increases the kinetic energy of the particles in the system, causing them to move faster and leading to an increase in temperature.
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.
