Work is a measure of newtons and this measure.
What is metre?
200
This is known as the force exerted on the machine.
What is the input force?

The amount of work done on an object if 10 N of effort force is exerted over 2 metres.
What is 20 joules?
400
This is the mechanical advantage of a machine with friction?
What is actual mechanical advantage?
400
A single fixed pulley such as a flagpole, changes this factor of the input force (hint: not the amount)
What is the direction?
