Jack: Don't you know how simple machines make your life easy?
Jimmy: Um... I don't know what simple machines are.
Jack: Simple machines are mechanical devices for applying force like a wedge or ramp.
Jimmy: Oh! wow! How I did not know this!
Jack: Like the wheels on hospital bed and IV pole. They help you move people faster by reducing the friction.
Jimmy: Is the stick over there that the TV is attached to, is that a simple machine too?
Jack: Yes it is, it's a lever. The wheels on the bus are simple machines, they make the bus move.
Jimmy: What about the doors?
Jack: 'Yeah' the driver pulls a lever and the doors open and you climb up the inclined plane aka the stairs. The cable in the elevator is wrapped around a groove in the wheel and axle, an electric motor pulls the cable, lifting the car between floors.
Jimmy: So the wheels on the rolling chair are too by rolling the chair back instead of lifting the chair back.
Jack: 'Yes' they are, they move the chair and reduce the friction.
