What is the upward force of air against a moving object?

Answer 1

= the (square of the velocity (m/s) * drag coefficient ) newtons

if terminal velocity is known (forces balanced , no further acceleration), drag coefficient can be found.

say terminal velocity(tv) = 70 m/s, acceleration due to gravity(g) = 9.8 m/s^2,

mass(m) = 80kg

m * g (force down) = tv^2 * drag coefficient (force up) at terminal velocity

then

m * g / tv^2 = drag coefficient

80 * 9.8/4 900 = 0.16

Answer 2

force (newtons) = (air) velocity2 * drag coefficient

some (typical) drag coefficients:

family car = 0.45

motorcycle = 0.25

freefaller = 0.15

note: velocity is in metres per second

Answer 3

The upward force of air against a moving object is called lift. It occurs when the object's shape and angle of attack create a pressure difference between the top and bottom surfaces, generating an upward force that opposes gravity. This principle is fundamental in aerodynamics and is essential for the flight of aircraft.

Answer 4

The upward force of a moving object is known as "lift".

Answer 5

air resistance

Answer 6

i think it's air resistance.

Answer 7

its called air resistance. I'm sure.

Answer 8

The force of air resistance is.
