Aerodynamics is the study of how air interacts with objects moving through it. Different vehicle designs are used for different purposes depending on how air forces act upon them. The main air forces are lift, which opposes gravity; drag, which opposes motion; and downforce, which increases tire grip for cars to take corners faster.

2. WHAT IS AERODYNAMICS ?
the study of the properties of moving air and the interaction between
the air and solid bodies moving through it.

4. EFFECTS PRODUCES BY MOVING FLUID ON A BODY
1: LIFT:- Lift is the force that directly opposes the weight of an airplane and holds
the airplane in the air
2: DRAG:-
3:- DOWNFORCE:-The purpose of downforce is to allow a car to travel faster through a
corner by increasing the vertical force on the tires, thus creating
more grip.
drag is a force acting opposite to the relative motion of any object
moving with respect to a surrounding fluid.
