Why does a manual transmission car jerk when the clutch is released?

[Etta]

Manual transmission cars jerk when the clutch is released too quickly, causing the vehicle to lurch forward or the engine to stall. Overcoming zero torque: When driving, the engine speed is relatively high, but the torque output from the engine to the wheels is zero. At this point, when starting, the car requires a relatively large torque to overcome forward or backward movement. Releasing the clutch too quickly: If the clutch is released too quickly when starting the car, it is equivalent to applying a large brake to the engine, preventing it from rotating, which can result in the car lurching forward or the engine stalling.
