1) it doesn't. Work = force x distance. So a pulley that reduces force will also increase distance -
but -
it can reduce the force needed to move something
thus making life easier.
Answer:
It depends on the number of pulleys and their arrangement. A single pulley does not change the force required to lift something. But, other pulley arrangements do. Four pulleys can be arranged into a thing called a block & tackle that can divide the force required to lift something by four. But, the rope must be extended four times as long to do this.

How does a pulley make your life easier?
A pulley can make your life easier by allowing you to lift heavy objects with less effort. By utilizing the mechanical advantage provided by a pulley system, you can distribute the weight of the load across multiple ropes and pulleys, reducing the amount of force required to lift the object. This can make tasks like lifting furniture, hoisting equipment, or raising sails much more manageable.
Does a pulley make work easier by changing the direction of force?
Yes, a pulley make work easier by changing the direction of the force needed to lift an object. It allows you to pull downward on the rope instead of lifting upwards, which can reduce the amount of effort required to lift the object.
How does a fixed pulley make work easier?
A fixed pulley changes the direction of the force applied to lift an object, without changing the amount of force needed. This makes it easier to lift heavy objects by allowing you to pull downwards rather than upwards.
How does the pulley make work easier?
A pulley makes work easier by reducing the amount of force required to lift an object. It does this by distributing the force needed to lift the object over multiple ropes and pulleys, which allows for the force to be shared among them, making the task easier to accomplish.
How does a single pulley make work easier?
A single pulley changes the direction of the force needed to lift an object, making it easier to lift by allowing you to pull downwards rather than upwards. It does not reduce the amount of work needed, but it helps in exerting the force in a more convenient direction.
How can pulleys make life easier?
The pulley makes work of lifting easier then lifting by hand.
How does a fixes pulley make doing work easier?
it deacreases the input force

Describe how simple machines make work easier?
Simply put, a simple machine makes the work much easier. Simple machines reduce the amount of force needed to do the work. A pulley, for instance, is a great example of a simple machine.
What are the use of pulley in simple machine?
it makes our work faster,easier and better
Why is a pulley is a lever?
Because they both reduce friction, making your work easier
