A simple first step is to determine kinetic energy of various vehicles:
KE = 1/2mv2
If you know the mass and velocity of an object, use the kinetic energy calculator to find its energy in movement.

Take a 2020 Ford F150 with a loaded travel trailer at a combined 16,000lbs (nearly maximum GCWR) traveling 83mph (maximum speed for most trailer tires).
That combo has about 4 million joules of kinetic energy that the brakes would need to dissipate.
Now look at a 2020 Mercedes Benz C63 AMG. Only weighs 4,400lbs, but has a maximum velocity of 175mph.
The C63 generates a maximum of slightly over 6 million joules of KE for the brakes to deal with.
This is obviously super simple and there are
many more variables, but it does outline the relationship between mass and velocity when it comes to energy.
FWIW, our demo F150 has 350mm rotors and the C63 AMG has 360mm rotors.
