Why do manual cars/motorcycles stall if you don’t give them gas as you let go of the clutch?

The car is big and heavy, and needs the engine running at a high enough speed to a) get it going and b) keep it going.
Engines have a power phase and a relaxing phase. So when youre pottering along the road, the car is going fast enough to keep the engine turning over it its relaxing phase.
But when it’s stationary, the engine will get the car going very briefly during the power phase but during the next relaxing phase it will just….stop. There’s nothing to keep the engine turning over until the next power phase because the car is still.

engines are built around using the inertia of the cylinders and crankshaft spinning to move them form power stroke to power stroke, and siphoning off the rest of the energy to do work. If you put too much load at once on the engine, you draw too much energy “out” of the system and then cylinders fail to properly compress the fuel to power the next cycle, dont ignite properly, and then theirs no more power for the next cycle.
modern engines use an electric starter to get them going, which is basically a small electric motor to spin the crankshaft and cylinders. other engines might use the ripcord for the same purpose, or even the old school hand crank.

That’s not true, it stalls when one lets go of the clutch pedal to fast, because the gear wheels didn’t have enough time to get into correct position. At least it’s like that in cars, I don’t know about motorcycles.
Engines generate more power the faster they’re running (generally speaking).
In order to get the car rolling, you need enough power (torque) to overcome the cars inertia.
If you don’t give enough power the engine can’t complete its cycles and so it just stops running.
You can fix this by applying more gas and increasing the power output of your engine, or by lifting the clutch slower so that it slowly starts slipping and gradually bringing the car up to speed instead of dumping the entire weight of the car on the engine at once.
