45) Conserve momentum: avoid stopping
Avoid coming to a complete stop whenever possible (and when safe and legal of course). It takes much less energy to accelerate a vehicle when it's already traveling just a few kilometers per hour than it does from a complete stop.
While the title of 45) is good, the explanation is confusing. I maintain it doesn't take much less energy to accelerate a vehicle when it's already traveling compared to when it's stopped.
It takes about the same energy to accelerate a car from 60 to 61 mph as it does to accelerate a car from 0 to 10 mph.
