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 type of work is being done when pulling?
The same type as is done when pushing, shoving, rolling, lifting, wiggling etc. ... a force acting through a distance.
When a book falls from a shelf to the ground without anyone pushing it Is work is being done on the book?
Work is being done by the force of gravity. When the book falls to the floor, there's a force on it, and the force keeps acting on it as it covers the distance. A force acting through a distance is the definition of work. Maybe there's nobody pushing the book, but the force of gravity is pulling it down, and it's the force of gravity that does the work on the book.
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 occur in order for work to be done?
In order for work to be done there must be a Force F pushing over a distance D. Work=Force x Distance Work only is done in the direction of the Force.
If you push a box forward and the box moves forward what type of work have you done on it?
Yes. The "work" done, in the pure Physics definition, is the force you apply to the box to keep it moving, multiplied by the distance you keep pushing.

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

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).
Is pushing up against a wall doing work?

Is pushing up on box as you carry it down the hall considered work done?
No, it is not.

How do you know work is being done?
work is being done when you use energy
How much work is done by the surface molecules pushing upward on the object when it moved horizontally?
If there is no vertical motion, then no work is done by any vertical forces.
A student does 300 joules of work pushing a cart 3 meters due east then does 400 joules of work pushing the cart 4 meters due north the total amount of work done by the student is what?
700 joules
