ELI5: Why, in a car with a manual transmission, does the car turn of when you raise the clutch too quickly?
gpt
The engine is rotating.

The wheels are stationary.

The clutch "joins" the engine to the wheels (basically).

If you immediately join - in effect - the rotating engine to the stationary wheels one of two things happen:

\- The wheels move.  You will jerk forward a little.

\- The engines stops rotating.  The engine will stall.

This is known as a stall, because you have literally stopped the engine from moving.  An engine that stops moving cannot "recover" from that, because it relies on constantly keeping moving all the time in order to run.

If you raise the clutch slowly, both the above happen but in a much more minor and gentle capacity - the engine will slow, and the wheels will start to accelerate.  In other words, your RPM will drop, but your car will start to pull away.

Doing it rapidly basically locks the engine, so it can't move around to the next combustion cycle, so it stops quite harshly.  A stall.
