Good question! That would take a long time to answer in full, but basically it is the combustion engine that makes it work. In the engine, fuel is burnt and the heat created from this is turned into motion to make the wheels turn. Its much more complicated in practice and involves lots of very impressive engineering. Have a google there’s some good website on how cars works and if you have any particular questions give me a shout 🙂

so is it like friction

????

There is some friction in the engine but we try to reduce it. Friction is useful between the tyres and the road because it stops the car sliding. In the engine we want to change as much of the heat in the movement energy to turn the wheels so friction would waste some of that energy. That’s what engine oil is for, the petrol/diesel fuels the engine but the oil is used to lubricate the parts so they move easily without friction.
