Cars don't move without engines.
There already has been. It's called the electric car
On cars with a carburetor you must press on the gas pedal to activate the choke, cars with fuel injection do not have a choke so this is not necessary.
solar cars get energy from the sun and transfur it in to electricity gas cars burn gas to make electricity
A gas is something without a fixed shape or volume because its particles are widely spread out and move freely.
done properly, not really. most cars can handle a low percentage (maybe 5-10%) ethanol in their gas without harm. It will, however, reduce gas mileage.
A car will move when the gas pedal is engaged. You can control the speed of the car by the pressure you put on the gas pedal. The brake pedal will either slow the car down or stop the car entirely.
The carbon footprint of a car is primarily its gas use efficiency meaning the number of miles it will travel per gallon of gas. Since all cars, old and new, burn gasoline and produce carbon dioxide to move the car, the more miles you get per gallon translates to fewer gallons of gas used to move the car. This applies to straight gas cars and hybrids (not plug in hybrids) since they all get their primary energy from gasoline.
All depends on your cost range. Hybrids are great because they don't rely on gas. Small cars are great because they are lighter and therefore don't take as much power to move. Do not, however, buy and SUV. they are gas guzzlers and you will be paying more for gas.
Solar powered cars are shaped differently because 1. The cars need to be aerodynamic to move faster, and 2. The shape collects more sunlight to power the car
to help cars and people get to place to place without wheels cars , bus and trains could not move
you step on the gas that's how cars move isn't it
