Revolutions per minute

Revolution per minute, or RPM, is like counting how many times a wheel goes around in a circle in one minute. Do you remember playing with a toy car and spinning its wheels? That's what we're talking about.

Take the wheel of a car as an example. When you go for a ride, the wheel spins lots of times per minute. We use RPM to count these spins. So, imagine you're watching the wheel while your parent drives the car, and you count how many times the wheel makes a full turn around in one minute. That's the RPM.

The speed depends on how fast the wheel is turning, and that's determined by how fast the car is moving. If the car is going faster, then the wheel is spinning faster and generating a higher RPM. If the car is going slower, then the wheel is spinning slower and generating a lower RPM.

RPM is essential for many machines and vehicles such as cars and bikes. By measuring RPM, we can tell how fast they are going and how well they are working. So, next time you're in a car or playing with a toy car, remember that the wheel is spinning really fast, and we use RPM to count how many times it is spinning in one minute.
