Work is done when a force is applied to an object and it causes the object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance the object moved in the direction of the force. If there is no movement or if the force is not in the same direction as the movement, then no work is being done.
Yes, when work is done on an object, its energy is typically increased. This increase in energy can manifest as changes in kinetic energy, potential energy, or a combination of both, depending on the nature of the work being done.
No work is being done by the automobile if it is standing still with the engine running since it isn't in motion (not counting any work done by the vibrations transmitted to the air and ground upon which it rests). The engine, on the other hand IS doing work while idling since the parts inside are moving and both having work done on them and, in turn, performing work on other parts.
Answer #1:YES======================Answer #2:No
The force that allows work to be done is applied force. When an external force is applied to an object, it can overcome resistance and cause the object to move, resulting in work being done on the object. This force is typically in the direction of the displacement of the object.
When a system is doing work, it can either increase or decrease in temperature depending on the type of work being done. If work is done on the system, its temperature may increase due to the input of energy. Conversely, if the system is doing work on its surroundings, it may lose energy and decrease in temperature.
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.
The answer depends on whether it is being picked up from a height that is greater or less than where it is put down.
The amount of work done to produce a sound determines the amplitude of a sound wave. Amplitude is the measure of the energy carried by a sound wave, with higher amplitudes corresponding to louder sounds.
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 amount of work done on an object is determined by the force applied to the object and the distance over which the force is applied in the direction of the force. The work done is calculated by multiplying the force by the distance traveled in the direction of the force.
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.
