I only consider the behavior of the bb after it leaves the barrel. I do this through measuring the velocity and angular velocity of the bb once it leaves the barrel.
Hello,
I would like to ask one question. What is the equation for the lift force of a rotating sphere when flying through the air:
m = 0.25 g
v = 130 m/s
angular velocity = 105 rad/s
radius = 3 mm
air density = 1.2292 kg/m^3
air pressure = 101200 Pa
air temperature = 15 °C = 288.15 K
If anyone...
