* Engine (or Motor): This is the power source. In gasoline-powered cars, the internal combustion engine burns fuel to create energy. Electric cars use electric motors powered by batteries. The engine's power is transferred to the wheels.
* Transmission: This system manages the transfer of power from the engine to the wheels, adjusting the gear ratios to provide optimal power and speed depending on the driving situation. Automatic transmissions do this automatically, while manual transmissions require the driver to select the gears.
* Drivetrain: This connects the engine/motor to the wheels. Different drivetrains exist (front-wheel drive, rear-wheel drive, all-wheel drive), each distributing power differently.
* Wheels and Tires: The wheels, rotating on axles, are the points of contact with the road. Tires provide the grip necessary for traction and control.
* Steering System: This allows the driver to control the direction of the car. The steering wheel is connected to the wheels via a system of linkages or electronic controls.
* Braking System: This enables the driver to slow down or stop the car. It uses friction to convert kinetic energy into heat, slowing the rotation of the wheels.
* Suspension System: This absorbs shocks and bumps from the road, providing a smoother ride and better control.
In short, the engine creates power, the transmission and drivetrain deliver it to the wheels, the steering system controls direction, and the braking system controls speed. The suspension system improves the ride and handling. All these systems work in concert to allow a car to move, steer, and stop.
