B) output force
Explanation
state of a body that moves freely in any manner in the presence of gravity
This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force.
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load
so, the answer is
B) output force
