What is combustion reaction:
Happens when an oxidant and fuel react.
Produces light and heat

Fire triangle:
Refers to heat, oxygen and fuel.

Activation energy :
The energy needed for a reaction to occur

Heat and energy is a necessary part to the fire triangle because:
The heat makes it possible to heat up the fuels energy.

How is the cook top of your stove a real life example of a fire triangle?
The stove uses energy, heat and oxygen to cook food.

Combustion Engine:
An engine in which the combustion of a fuel occurs with an oxidizer ; mainly air.

How combustion engine works:
Fuel is burned inside the engine in a combustion chamber.
Gasoline creates energy by expanding. More compressed the mixture of the air and fuel,
a higher chance of it burning .

More combustions ; makes it go faster Home made . Bodies are made from flat sheet metal. No mufflers so nitrous oxide is needed.Http://www.auto.howstuffworks.com/auto-

They have mufflers so they don’t need nitrous oxide.
Engines are smaller. Run slower.

How nitrous oxide help an engine perform better:
Because there is more oxygen available during combustions mean more fuel will be able to inject to produce more power ; therefore the car will go faster.http://auto.howstuffworks.com/question259.htm

NASCAR CHEATER!
Winner’s Jimmie Johnson's and second place driver Kyle Busch's cars failed post race inspection. The roof of Jimmie Johnson's car was too low. Kyle Busch's car had an quarter-panel heights that were too high, an aerodynamic advantage.
