AS REPORTEDno primary record reached; this is what the reporting says
Available physical analyses confirm that applying brakes while a vehicle is airborne transfers angular momentum from the wheels to the chassis, thereby affecting its pitch rotation.

## Question
In a racing video game series named Trackmania, there is a game mechanic where when you hit a jump and the car is in mid-air, you can stop the car from pitching downward by tapping on the brakes.
I am curious if this mechanic has some basis in real physics. What would happen if a car were pitching nose down while in the air, and you hit the brakes thus stopping the rotating wheels. Would that affect the car's pitch, and if so, how?

It will affect pitch, but not the way it works in the game. In the game, braking while in the air stops your pitch axis rotation. In real life, it does something completely different.
The wheels have angular momentum. When the wheels are slowed, this angular momentum must be conserved. This results in a transfer of angular momentum from the wheel to the vehicl
