My partner has been asking me how tires spin (specifically on cars) and I don’t know how to answer. How do they spin without coming loose? How do they understand the speed you want them to go?
Thanks in advance!!

they “understand” the right speed because that’s how fast the engine is spinning, which is because (simplified) of how much gas you give it through the gas pedal. In an electric car, the “gas” pedal is just an electric sensor, which sends a signal to some computer chip in there to tell the battery to give the electric motor more power.
