% Drag=0.5*rho*v^2*S*Cd

% Density of air
rho = 1.225

%Drag Coefficient; Flat Plate=1.28,Prism=1.14,Bullet=0.295,Sphere=0.07,Airfoil=0.045
CD = [0:25]%Lowest and Highest value of CD of Various Objects
% Frontal Area
A = 0.1

% Velocities
V = 15; %Typical Bicycle Velocity
v = [0:25]

Drag_Calc1 = 0.5*rho*A*CD.*v.^2
Drag_Calc2 = 0.5*rho*A*CD.*V.^2
