what is the formula for deriving energy lost due to air friction??
Answers
Answer:
Explanation:
Air resistance is also called "drag", and the unit for this force is Newtons (N).
F= kv²= (ρ*CD*A/2)v²
F = force due to air resistance, or drag (N)
k = a constant that collects the effects of density, drag, and area (kg/m)
v = the velocity of the moving object (m/s)
ρ = the density of the air the object moves through (kg/m3)
CD = the drag coefficient, includes hard-to-measure effects (unitless)
A = the area of the object the air presses on (m2)
