Explanation:
A lever works by reducing the amount of force needed to move an object or lift a load. A lever does this by increasing the distance through which the force acts. ... You will see that levers neither increase nor decrease the amount of total effort necessary.
Answer:
Levers are used all over the place in our everyday life. But have you ever wondered just exactly how they work? Grab your favorite budding scientist and tackle this fun project — and before you know it, you’ll both be lever experts!A lever works by reducing the amount of force needed to move an object or lift a load. A lever does this by increasing the distance through which the force acts. In this experiment, you will show that the closer the fulcrum — or the pivot point of the lever — is moved toward the load, the less effort is required to lift the load. At the same time, the distance over which you must apply the force increases. You will see that levers neither increase nor decrease the amount of total effort necessary. Instead, they make the work easier by spreading out the effort over a longer distance
