The Science of CO2 Dragsters

Element- A substance that contains only

one kind of atom.

Atom- The smallest unit of an element that retains the chemical

properties of that element.

Compound- A substance consisting of two or

more different elements chemically bonded together.

Carbon DioxideCO2

Force- A push or a pull

Newton’s third law of motion for every action (force) there is an equal and opposite reaction (force).

Forces acting on your C02 car.

Gravity- The force of attraction between objects of mass. Earth’s gravity pulls objects towards its surface.

Lift- The force that opposes gravity.

Thrust- The forward force generated by propulsion.

Drag- The force that resists the forward motion of a solid object in a fluid.

Friction- The property that objects have which makes them resist being moved across each other.

3 kinds of friction…Sliding (kinectic) friction- produced when two surfaces slide across each other.Rolling Friction- resistance produced when a rolling body moves over a surface.Fluid Friction- The friction between a fluid (air in the case of CO2 cars) and an solid (the CO2 car).

Newton’s first law of motion states that an object at rest tends to stay at rest unless acted upon by an unbalanced force, and an object in motion tends to stay in motion going the same speed and direction unless acted upon by an unbalanced force.

Aerodynamics- Is the study of forces that act on an object as it moves through a fluid.

Streamline- the flow of air moving around an object. The teardrop is the most aerodynamic and streamlined shape.

Eddies- a current of fluid or air running against the main current causing the swirling of air molecules.

Newton’s second law of motion which states that acceleration is produced when a net force acts on a mass. The greater the mass of the object being accelerated, the greater the force is needed to accelerate the object (F=MA).
