Question

formula for finding air resistance​

Answer 1

Explanation:

Air resistance can be calculated by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.

Answer 2

Air resistance is a force that affects objects that move through the air. Often physics problems used in teaching ignore it, but it is very important for understanding the motion of fast-moving objects like airplanes. It depends on the density of the air, the area of the object, the velocity it is moving, and a "drag coefficient" that accounts for other properties of the object like the surface roughness, and turbulence. Air resistance is also called "drag", and the unit for this force is Newtons (N).

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)
