Don't really know what you're after here...
The bicycle as a whole keeps moving due to something called inertia. Inertia means that an item prefers to keep doing what it was doing the moment before. If it was stationary it takes an effort to get it moving, if it's moving it takes an effort to stop it.
Unless you're heading downhill, or have a strong tailwind, in which case it's gravity or the tailwind that keeps you moving.
THe other posssible thing you're after is the one-way clutch thingy stuck in most rear wheels. Depending on bike it'scalled either a freewheel or a freehub, and it allows the pedals to hook on when pushed forward, and to disengage if the wheel is moving by itself.
it's because of friction. There's friction around the axles of all the spinning parts, there's friction against the air as the bike travel forward. There's even a very special kind of friction called hysteresis in the rubber getting deformed as the wheels roll along.
Friction is what ultimately stops your bike
If the bike has a license, then it is an official vehicle and you need to ride it on the road and stop for the ambulance and get on the shoulder of the road.
You push the brake.
After an emergency stop on a bike, you need to start on a low note and low speed. You will keep accelerating as you gain momentum.

Yes, pay what you owe on it.

Stop bike and get in car
THe brakes rarely need to stop. But the brakes can be used to make the bike stop.
There are a few ways. 1) Firstly, use "engine braking" to slow the bike to it's slowest, powered, speed, then pull in the clutch to be able to use your foot to slow and stop the bike. 2)Lay the bike down (usually done to avoid accidents). This usually happens on the bends when the bike is sideways. You simply move your weight further away from the bike and let it drop ot the floor and slide to a stop 3)Hit the fence - NOT the best way to stop.
No, but it is frowned upon. Some cities have bike lanes to stop people from riding on sidewalks.
The truck it has more weight behind it.
