MCA: C02 Cars

What powers C02 cars?

• Carbon Dioxide

• Carbon Monoxide

• Nitrous Oxide

• A tiny engine

What is the most important factor that affects how fast your C02 dragster will race?

• Friction

• Mass

• Thrust

Thrust is defined as.......

• the propulsive force of a jet or rocket engine

• the quantity of matter which a body contains

• the resistance that one surface or object encounters when moving over another

Friction is defined as .........

• the propulsive force of a jet or rocket engine

• the quantity of matter which a body contains

• the resistance that one surface or object encounters when moving over another

Mass is defined as ........

• the propulsive force of a jet or rocket engine

• the quantity of matter which a body contains

• the resistance that one surface or object encounters when moving over another

Thrust occurs as a result of ____________.

• The race pin pushing on the back of the car

• The C02 gas escaping from the container

• You pressing the race button

The resisitance force of the air pushing against the car's body as it races down the track is called _________.

• Momentum

• Potential Energy

• Drag

Newton's ______ law of motion that's responsible for the gas rapidly escaping from the C02 cartridge to push the car down the track.

• first

• second

• third

Since the C02 cartridges contain an equal amount of gas being released at the same speeds, the car that wins the race is the one that is the _______ & ________.

• heaviest; most stable

• lightest; most aerodynamic

• best painted; best decorated

How do you overcome Friction when designing and building your CO2 dragster?

• add more paint

• use spoilers and body add ones

• make sure the moving parts are free to rotate and don't rub on the body

• have a freshman make it
