❓ Frequently Asked Questions
What is aerodynamics?
The study of how air interacts with moving objects, shaping forces like lift, drag, and stability that affect performance and efficiency.
What factors determine lift on a vehicle wing or airfoil?
Lift depends on air density, speed, surface area, and the lift coefficient (L = 0.5·ρ·V^2·A·Cl); increasing any of these (where appropriate) increases lift.
What are the main types of drag that affect vehicles?
Parasitic drag from form and surface roughness, and induced drag from generating lift; both oppose motion and reduce efficiency.
What is downforce and why is it important for vehicles?
Downforce is a downward aerodynamic force that pushes the car toward the road, increasing tire grip and stability at speed.
