– Why do people say that driving a car at the same speed consumes less fuel in comparison to driving it at varying speeds over long distances
In: Physics
A car moving at constant speed doesn’t require any additional energy to keep moving. It only takes energy to stop, speed up, or change direction. Likewise, if a car is stopped, it doesn’t require energy to just sit there. It only takes energy to make it move. The most energy consuming part of your drive is making the car go faster, especially from a stopped position.
In other words, it takes a lot more energy to go from 0-60 than to just keep going 60. If you brake and accelerate a lot, you kind of are wasting gas.
