Work performed on a machine?
The work done by a machine is called work output
What is work done on a machine called?
Machine work
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
How do we know if work is done?
In physics, work is done by a force acting on an object if the object moves in the direction of the force.
If a force of 100 newtons was exerted on an object and no work was done the object must have?
The object must be stationary. Work done happens when the object is moving in the direction of the force- if it is staying still, there is no work done!
What is the work done by a machine on an object called?

A machine lifted a 1000 n object 40 meters in 15 seconds how much work is done by the machine?
work = f x s. work = 1000 x 40 40000J
What is work done on a machine called?
Machine work
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
What is the differences between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
What is the difference between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
What is the work done by a machine on a machine?
Power
How can work be done?
Work done when force moves an object.
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
Differences between input work and output work?
Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.
How do we know if work is done?
In physics, work is done by a force acting on an object if the object moves in the direction of the force.
