Force changes either the speed or the direction of motion, or both.
A machine that changes only the direction of force has a mechanical advantage of 1. This is because it does not multiply the input force, but rather changes its direction to make work easier.
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
The force that changes the direction of a compass needle is called the magnetic force, which is generated by the Earth's magnetic field.
Pulleys change the direction of a force.
The change in direction of an object when a force is applied to it is called "acceleration." The acceleration of an object depends on the magnitude and direction of the force, as well as the mass of the object.

A fixed pulley changes the direction of the input force without changing the amount of force applied. It is attached to a fixed point and does not move, simply redirecting the force in a different direction.
The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
