WebbOf course, the drag equation is itself a model, based on the assumption that \(C_d\) does not depend on the other terms in the equation: density, velocity, and area. For objects moving in air at moderate speeds (below 45 mph or 20 m/s), this model might be good enough, but we will revisit this assumption in the next chapter. WebbF d is the frictional force – known as Stokes' drag – acting on the interface between the fluid and the particle (newtons, kg m s −2); μ (some authors use the symbol η) is the …

Webb1 nov. 2016 · Drag cannot make anything fall (drag would then start working to slow the fall). Force = mass * acceleration, so acceleration = force / mass. Acceleration is the change in velocity. There are three separate forces acting on your rocket: The thrust of the rocket, gravity and drag. Webb12 apr. 2016 · The drag equation can be written as v ′ ( t) = α v ( t) 2 for some constant α (which you have to work out: it depends on p, C D, etc.). The equation v ′ ( t) = α v ( t) 2 is a first order differential equation which you have to solve to get the function v ( t).
