It's a pretty incredible amount of energy. Just think if you put a gallon of gas in a car than hit the petal, then lets take away (or at least mostly minimize so that the car has same aerodynamics as a artillery shell) air resistance for fun. The car accelerates until it burns through a gallon of gas, so for maybe, what 10-30 minutes depending on the vertical it's constantly accelerating, I can even imagine what speed it could get up to if you discount mechanical limitations of the engine/tires/etc, but let's say at least 1000 mph, conservatively. Then car runs into a brick wall. That is the amount of energy in a gallon of gas.
- metaphorm 12y agoits way more energy than that! car engines aren't even close to 100% efficient. all the heat that blows out your exhaust pipe is energy that the engine couldn't capture. ditto for heat of friction on the mechanical components, and heat that radiates into the air from the engine block.
- stolio 12y agoFor fun, KE = (1/2)mv^2 = 32 MJ -->[mathing intensifies]--> a 1,000 kilogram car moving at about 565 mph carries 32 MJ of energy, which is what 1 liter of gasoline carries. A gallon is about 4 liters, so at 100% efficiency it could get a 1,000kg car to ~1,130 mph or a 1,500kg car to ~925 mph. For reference, the same calculations tell us a quarter-pounder with cheese could get a 165 lbs (75kg) human up to 540 mph.
