A simple pulley primarily accomplishes two things:
1. **Change of Direction**: It allows the direction of the force applied to lift an object to be changed. For example, pulling down on one side of the rope can lift an object upward on the other side.
2. **Force Distribution**: It can provide a mechanical advantage, making it easier to lift heavy objects. Although a simple pulley does not reduce the amount of work done, it can make it easier to apply the necessary force by allowing the user to pull at a more convenient angle.
Overall, the simple pulley is a useful tool in mechanical systems, facilitating lifting tasks by changing the direction of the force and potentially easing the lifting process.
