Which is an example of a way that machines make work easier? They increase the time it takes to do a task. They spread a small force over a small distance. They spread a small force over a larger distance.

The correct example of how machines make work easier is: **They spread a small force over a larger distance.** ### Explanation: Machines often utilize the principle of **mechanical advantage**, which allows a smaller force to accomplish the same amount of work by increasing the distance over which the force is applied. This means that while the force required is reduced, the distance the machine moves the load is increased. **For example:** - **Lever:** By applying a smaller force over a longer distance on one end of the lever, you can lift a heavier load on the other end. - **Pulley Systems:** Multiple pulleys can reduce the effort needed to lift an object, but the rope must be pulled a greater length. This approach makes tasks easier by requiring less effort from the user, even though the total work done remains the same. ### Why the Other Options Are Incorrect: - **They increase the time it takes to do a task:** Increasing the time required does not make work easier. In fact, it could make a task less efficient. - **They spread a small force over a small distance:** This does not provide a mechanical advantage and doesn't effectively reduce the effort needed. **Summary:** Spreading a small force over a larger distance is a fundamental way machines make work easier by providing mechanical advantage. **Answer:** They spread a small force over a larger distance.
