Well, honey, a domino is a classic example of a class 1 lever. The force (effort) is applied to one end, causing a rotation around a fixed point (fulcrum), and the other end moves the load (domino). So, next time you line up those dominoes, just remember you're basically playing with physics!

A domino can be considered a class 1 lever where the pivot (fulcrum) is at one end, the force (push) is applied at the other end, and the load (domino) is in between. This is similar to a seesaw.
Yes, it is a 3rd Class Lever.
A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.
First Class LeverIt is a First class lever.
Ice tongs are a class 3 lever because the effort is between the fulcrum and the load.
No, a nail cutter is not a first-class lever. It is a type of lever called a third-class lever because the effort force is between the fulcrum and the load.
