Answer:
Force is a vector quantity which when applied to an object can cause change in its velocity. When Force is applied to an object, the object if stationary moves to a certain distance depending upon the amount of force applied.
A pulley is a wheel with a groove that holds a rope, cable or belt, and is used to help lift an object.
The relationship of Force and Distance is the same for a fixed pulley as well. Except for one thing:
Normally the distance covered by an object is in the direction of the Force.
Using a pulley, an object can be moved with that same Force in a different direction. Using a pulley, a person can apply force in a direction suitable for him while moving the object.
Force = mass of an object * Distance Covered
