This works in reverse for braking of course since then inertia has its biggest effect at the highest speeds when you attempt to slow down.
I know many here understand this thoroughly, but the majority on the board likely do not.

The same can be said about the total vehicle mass when looking at acceleration. This is why "equivalent mass" is so convenient, it depicts well the impact that rotating mass has on the overall mass of the vehicle and can be used in F=m
ea (where m
e is equivalent mass).
