1. AERODYNAMICS & THE FOUR FORCES

2. What is AERODYNAMICS
AERO = AIR
DYNAMICS = MOTION

3. THE FOUR FORCES
LIFT
THRUST
DRAG
GRAVITY

4. THRUST To move forward the car needs thrust.
Thrust depends on the size of the car in relation to engine.
Thrust is used to overcome drag.

5. DRAG
As the car moves forward the air resists the motion, this is drag.
Drag is directed along and opposed to the direction of movement.
The shape, and velocity of the car will affect drag.

6. LIFT Lift is generated by the motion of the car through the air.
The magnitude of Lift depends on shape, size and velocity of the car.
Lift is the opposing force of gravity.

7. GRAVITY
Gravity is a powerful force directed toward the center of the earth.
Gravitational force depends on the mass of the object.
