How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

Someone rear-ended me the other day. The car's still driveable, but I'm worried it might be a write-off because it's such an old car.
Feels bad.

If a plane stays still in the air for 10 hours and doesnt move, why doesnt the plane end somewhere afterwarda, because the earth is spinning, right?

Nick Terry says:

Robots don't like acceleration either! My team built a computer for use on a battleship. They need to be shock tested and a surprising number of good computer parts can't handle the acceleration.

Ah very informative. It is astonishing to know what level of engineering and Physics goes into making cars and other machines of our daily lives. Thanks for such a nice video.

Useless knowledge that everyone already knows and would only take 3seconds to explain, you are just making this crap because Ford payed you money.

0:35 sperm + cup = car ?

fenhen says:

Anyone else think those teaspoons were sperm?

Can you explain to me this. When i fart in a bus.Lets say im sitting in the back, how can someone smell it in front of the bus? i want to know what smell is? i fart a very little supstance but the whole bus can smell it? how is it possible? And its the same thing like lions smelling blood from half a killometar? I would be very thankfull if ylu do a video about this

It takes 5 sperms of gas to accelerate a car……

The safest place to put a metal spike in a car is the center of the steering wheel. Would you drive unsafely if there was a metal spike aimed at your chest?

lol, 0:30, looks like five sperm cells

Zoravur Singh says:

Wow, car engines are maddeningly innefficient.
