Simple machines increase mechanical advantage, allowing a user to apply less force to accomplish a task. They achieve this by changing the direction of the force or by distributing the force over a longer distance. This makes it easier to lift heavy objects, move them, or perform work with reduced effort. Common types of simple machines include levers, pulleys, inclined planes, wedges, screws, and wheel and axle systems. Each of these machines helps to amplify force, making tasks more manageable.
