Answer

A pulley changes the direction of the force, making it easier to lift the bucket of water.

Solution

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.

Extra Insights

The pulley makes work easier primarily by changing the direction of the force needed to lift the bucket. Instead of pulling straight up, the user can pull down on the rope, using their body weight and gravity to assist in lifting the bucket. This simple shift can create a more ergonomic lifting action, making it less strenuous! Additionally, using a pulley system can also reduce the effort required. While it doesn’t literally increase the amount of force, it allows for a mechanical advantage: with a well-placed pulley, you can lift heavier buckets with less physical strain. So, users can fill their buckets to the brim without feeling like they've just wrestled a bear!
