Why is work done with a machine is the same as work done without a machine?

In an ideal scenario, the work done with a machine is the same as work done without a machine because the total work output must be equal to the total work input. While machines can make work easier by multiplying force or changing the direction of force, they cannot create energy. Therefore, the work done by the machine should ideally be equal to the work done without a machine.


How does the work done a machine compare to the work done by a machine?

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.


Why can't the work done by a machine be greater than the work done on the machine?

According to the law of conservation of energy, energy cannot be created or destroyed, only transferred. Therefore, the work done by a machine cannot be greater than the work done on it because the input work is what provides the energy for the output work. Any excess work would violate this principle.

What s not changed when work is done by a machine?

When work is done by a machine, the fundamental principles of physics governing the conservation of energy and conservation of momentum remain unchanged. These laws dictate that energy cannot be created or destroyed, only transferred or converted, and that momentum will be conserved in any isolated system.

Do you have a microdermabrasion procedure that is done by hand, not machine?

I can assume it's for Amtrak but I cannot assume what time of day the person wants as the prices will vary.
