Because the driver doesn't want any of the passengers to get hurt. If you didn't put a seat belt on then you would just fly forward and hit/crash into the window or the seat in front of you. That is why you wear a seat belt and the reason why the car jerks when the brakes are put on is because no one wants to get into a crash or a car accident.
1. Put the engine in a lower gear and leave the clutch slowly. Vehicle will stop with a jerk. 2. Use parking brakes
The vehicle will pull to the side with the blown tire. If you do not panic and just let off the gas and slowly apply the brakes you will not have an accident. If you jerk the wheel or slam on the brakes you will loose control.

Take your foot off the accelerator, and slowly move back on the road. Do not jerk the wheel or apply the brakes.
The year, make, model, transmission and engine info would help but it is probably the transmission down shifting if the vehicle is an automatic.
It is important for a vehicle to run smoothly, and give the passengers a smooth ride. The cause of this vehicle jerking could be due to lack of electrical flow, lack of fuel or the computer going bad.
STICKING BRAKE CALIPER
There are many examples of inertia of rest. This can include the way your body moves when a car suddenly has to apply the breaks. It can also be seen when you flick a pencil that is laying on a table and the pencil begins to roll.
When a driver suddenly applies the brakes, the car decelerates rapidly, but your body continues moving forward due to inertia, the tendency of objects to maintain their state of motion. This forward movement happens because your body is not directly attached to the vehicle’s braking system. As a result, you experience a jerk as your body lags behind the car's sudden stop. This phenomenon is a basic principle of physics that explains how forces affect motion.
One wheel of the brakes may be "grabbing" because of cracked brake linings or broken hardware. Have the brakes safety inspected soon!
if the car jerks when the brakes are applied it is likely that the brake rotors are warped
