How does the pulley on the well in the picture make work easier when pulling up a bucket of water? It adds weight to the bucket. It changes the direction of the force. It increases the amount of force.

To understand how the pulley on the well makes work easier when pulling up a bucket of water, let's analyze the options provided: 1. **It adds weight to the bucket.** This statement is incorrect. A pulley does not add weight to the bucket; it simply helps in lifting the bucket. 2. **It changes the direction of the force.** This statement is correct. A pulley allows you to pull down on a rope to lift the bucket up. This change in direction means that you can use your body weight to assist in lifting the bucket, making it easier to pull it up. 3. **It increases the amount of force.** This statement is misleading. A pulley does not increase the amount of force; rather, it allows you to apply force more effectively. In some systems, multiple pulleys can reduce the amount of force needed to lift an object, but a single pulley primarily changes the direction of the force. In conclusion, the correct answer is that the pulley **changes the direction of the force**, making it easier to lift the bucket of water.
