In science (particularly physics) there are simple machines and complex machines.
A washing machine is considered a compound machine because it consists of multiple simple machines working together to perform a complex task. It typically includes components like a motor (wheel and axle), pulleys, and gears, which work in unison to facilitate the washing process. By combining these simple machines, a washing machine efficiently agitates, rinses, and spins clothes, making it a more versatile and effective appliance.
