When you start the engine of your car with the transmission in neutral, you notice that the car rocks in the opposite sense of the engine's rotation. Explain in terms of conservation of angular momentum. Is the angular momentum of the car conserved for long (for more than a few seconds)?​

Answer:

Adrian is exactly right. There is rotating mass in the engine. As you accelerate that mass from not running to running (starting the car), an equal and opposite force is applied to the frame and absorbed by the springs (the car rocks). Once the engine is running and the rotating mass is not being accelerated, the springs return that energy back to the frame (the car rocks back to level).
