A pedal is a part that helps control movement or sound in a vehicle, musical instrument, or machine.
Think about all the times you've ridden your bike or sat on the bus. You might have noticed those long metal things connected to the floorboards where your feet rest? Those are pedals! They help you push off and keep moving by allowing you to press down with your foot. It's like having an extra leg helping you move forward. And, if you play a musical instrument like a piano or organ, there are also pedals for making different sounds.
A lever operated by one's foot that is used to control or power a machine or mechanism, such as a bicycle or piano.
Example: There are three pedals on manual cars, two on automatics.
