In a pulley system, the mechanical force required to lift a block will change the direction of the force applied. Therefore, the correct answer is:
**decrease; direction of the force.**
Using pulleys allows a person to use less force to lift a heavy object, especially if the pulleys are configured in a way to provide a mechanical advantage. This means you can exert a smaller force over a larger distance to lift the load, and the direction of the force can be altered (e.g., pulling down on a rope to lift the block upward).
