A single pulley can change the direction of a pulling line. The direction change may help in pulling the line over a corner or around an obstacle. Or the direction change may allow better use of the available pulling force. Also, the single pulley can relocate the pulling point.
For example, suppose we wish to lift a weight some distance into the air. If I am the pulling force, then my first problem is that I cannot lift the weight any higher than I can reach. But if the pulling line is looped over a pulley some distance above my head, relocating the pulling point, I can potentially lift the weight just about up to the pulley's height. And now the pulley has given me another advantage. I can leverage my own weight, pulling down on the line, to lift the weight upward.

How would you describe a single pulley system?
describe a single pulley system
What is a single pulley system?
A single pulley system is simple. It's just when a pulley has just one wheel and carries less of a load.
What is the job of the single pulley?
A single pulley system is used to change direction of the pulling force line.
What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
What is a single fixed pulley?
A single fixed pulley is a simple machine that only changes the direction of the force applied, not the amount. An example is the pulley in window blinds.
Uses of single pulley?
it can help by pulling heavy loads using a rope
What are 2 different kinds of pulleys?
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)

The simple machine that provides a mechanical advantage of one?
Single fixed pulley
What is a single moveable pulley?
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
