We can change or shift vehicle weight by
a) change in speed (by accelerating and by braking)
b) change in direction (turning left or right)
Now there is a physics behind the shift in weight based on braking and accelerating.
You can shift weight to the front of your vehicle by braking.
Similarly, we can shift weight to back by accelerating.
Bending or turning left will transfer weight to right
Bending or turning right will transfer weight to left
