Here's how it works:
1. Chemical Energy in the Battery: The car battery stores chemical energy in the form of lead-acid. This energy is released through a chemical reaction when the battery is connected to the car's electrical system.
2. Electrical Energy: The chemical energy is converted into electrical energy by the battery.
3. Powering the Car: The electrical energy powers various components of the car, including:
* Starting the Engine: The starter motor uses electrical energy to turn the engine crankshaft, which in turn ignites the fuel.
* Running the Electronics: The electrical energy powers lights, radio, dashboard, and other electronic systems.
* Fueling the Engine: The electrical energy also helps ignite the fuel in the engine, which then releases combustion energy to power the car.
So, although the car ultimately runs on combustion energy from the fuel, the initial act of turning the car on relies on chemical energy stored in the battery.
