Explanation:
Detailed explanation-1: -Pulleys are simple machines that can change the direction of force, making it much simpler for us to move objects. They also increase mechanical advantage when we use multiple pulleys together. This process decreases the amount of force required to lift something up.
Detailed explanation-2: -Pulleys are mechanisms compost by wheel and rope used to lift heavy objects onto tall heights. They change the direction of an applied force and they can even reduce the force needed to lift a weight.
