Braking essentially turns gasoline into heat and brake dust, and it just so happens you slow you down.

Think about every time you ride a bike. Do you try and keep rolling as much as possible, or do you hit the brakes hard, only to have to pedal hard again to get back up to speed?

For accelerating, its the same principle as a bike. If you gradually come up to speed, you have time to use your gears efficiently and keep your cadence (pedaling speed) low. But when you are trying to get up to speed fast, you are more likely to pedal your legs really quickly, which does deliver a lot more power, but it is a lot more draining.

In a car, you are burning more fuel in the engine if you revv it really high, but it does get you up to speed quickly. By being more gradual, you are allowing the car to shift through the gears for the best advantage.
