When a top spins, there is a little bit of work being done: The top attempts to maintiain a conservation of angular momentum, which is why as the top slows, it tends to wander more and more across the table.
The rotational work formula is W , where W represents the work done in rotational motion, is the torque applied, and is the angle through which the object rotates. This formula is used to calculate the work done in rotational motion by multiplying the torque applied to an object by the angle through which it rotates.
work is being done when you use energy
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.
No, work is only done on an object when there is displacement in the direction of the force applied. If the object does not move, then no work is being done on it.
An example of work being done on an object is when a painter paints a canvas. The canvas is the object on which the work of painting is being done. The action of applying paint to the canvas is the work being performed on the object.
The keyword occurs when work is being done in the context of a search query or programming code.
work can only be done by a living being
It is work that is being done in a laboratory.
Yes it is.
you know when work is done when it's finished and checked and approved by someone.
Yes it is being done, if the person doing it is doing it as part of a paid job or because they run a business and the letter is needed for the business. If it is being typed for school it may also be considered work, but of a different kind. And from the view of physics, since energy is being expended by the person typing, and perhaps by the machinery being used, work is being done. However, if you are at work and typing a letter to your grandmother, that is not the kind of work you are being paid for and your employer would say work is not being done.
The work done by torque in rotating an object is the amount of energy transferred to the object to make it rotate. Torque is a force that causes an object to rotate around an axis, and the work done by torque is calculated by multiplying the torque applied to the object by the angle through which the object rotates.
