Answer :- The pulley reduces friction.
The main advantage of using a pulley system compared to just running the rope over a branch is that the pulley reduces the amount of friction and effort needed to lift objects. By passing the rope upward and through a single pulley, the load is distributed more evenly, making it easier to pull downward to lift the object.
Passing a rope upward and through a single pulley increases the mechanical advantage, making it easier to lift heavy objects by applying less force. This setup also allows for better control and direction of the lifted object compared to just putting the rope over a tree branch.
Reduces friction and makes it easier to lift the object by changing the direction of force.
Passing the rope upward and through a single pulley creates a mechanical advantage, making it easier to lift the object with less effort. The pulley reduces the amount of force needed to lift the object by distributing the weight across multiple strands of the rope. This configuration also allows for a smoother and more controlled lifting motion compared to just pulling the rope directly over a branch.

The pulley wheel will turn and cause less friction. The rope over a branch will have a lot of friction, so is harder to pull, especially if the load is heavy.
