These three simple machines all alter force in such a way that it makes it easier to move an object. You might not have noticed, but we use these simple machines all the time. Every time you sweep the floor with a broom you're using a type of lever.
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers). It all depends on where the fulcrum point is as compared to the load point.
