CO2 Dragsters

Aerodynamics

• Aerodynamics is the way air moves around things.

Drag

• What is Drag?
• Drag can also be called air resistance.
• Drag is generated by the interaction and contact of a solid body with a fluid (liquid or gas).

​

Friction

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

​

Mass

• Mass is a measurement of the amount of matter something contains.

Gravity

• Gravity is a force which tries to pull two objects toward each other.
• Anything which has mass also has a gravitational pull.
• The more massive an object is, the stronger its gravitational pull is.

​

• Gravity is what gives you weight.
• It is the force that pulls on all of the mass in your body.

​

• Earth's gravity is what keeps you on the ground and what causes objects to fall.
• Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth.

Potential Energy

Potential energy is energy that is stored within an object, not in motion but capable of becoming active.

Kinetic Energy

• Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles.
• Any object in motion is using kinetic energy: a person walking, a thrown baseball, and a crumb falling from a table

Inertia

• A property of matter that causes it to resist changes in velocity (speed and/or direction).

Aerodynamics

• Aerodynamics is the way air moves around things.
