Some examples of devices that do not use electromagnets include simple mechanical tools like hammers and screwdrivers, as well as passive devices like a piece of rope or a wooden stick. These devices do not rely on electromagnetic principles for their operation.
A person kicking a ball involves the use of a lever. The leg acts as the lever, the foot applies the force to the ball, and the ball is the load. This interaction demonstrates the principles of a lever in action.

They are commonly referred to as floaties.
Seesaws are not classified as inclined planes; instead, they are a type of lever. While both devices use the principles of physics to balance forces, an inclined plane is a flat surface tilted at an angle to help lift objects with less effort. Seesaws pivot around a fulcrum and allow two people to lift each other by shifting their weight. Thus, although they share some mechanical principles, they belong to different categories in physics.

One use of a lever is a wheelbarrow.
Probably you are using the board as a lever.
You Use A Lever CORRECTION: You use a LeveL, not a LeveR. LEVEL!
Whether something is a lever depends on how you use it. The most obvious thing to use as a lever would be a ruler, but conceivably you could use a pencil in that way, and scissors are necessarily levers.
