In physics work is dome when a force acts on a body and the body moves in the direction of the force.
In order for work to be done, two things must be present: force and displacement. Force is applied to an object to move it, causing it to undergo a displacement in the direction of the force. Work is calculated as the product of force and displacement in the direction of the force.
No, doing work requires the application of a force that causes displacement in the direction of the force. If an object remains at rest, no work is being done on it. Work is only done when both force and displacement are present in the same direction.
The formula to calculate work done per person is: Work done = Total work / Number of people. This formula divides the total work required to be done by the number of people doing the work to determine the work done per person.
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
