If the mechanical advantage is equal to 1.....
...REQUIRES THE USER TO APPLY AN EFFORT FORCE TO THE LOAD FORCE
...THE LOAD IS NOT MOVING
...MEANS THAT THE USER NEEDS TO APPLY A GREATER EFFORT FORCE TO PUSH THE MACHINE FORWARDS. AS A RESULT THE MACHINE GOES FASTER AND FURTHER.
...ALLOWS THE USER TO MOVE A LARGER LOAD WITH A RELATIVELY SMALL EFFORT FORCE

What is mechanical advantage?
The advantage a machine has over a bicycle
A measure of how much a simple machine reduces work
A measure of when is the best time to use a simple machine
the number of times a machine increases input force
If a pulley system has a mechanical advantage of 4, what does that mean?
This means that it is 4 times easier to lift this load.
This means you only need a quarter of the effort to lift the load.
For example, if you lifted 100 kg, it would only take 25 kg of effort.
All of the above
