AI Thread Summary
Air drag is influenced by velocity, and it is generally accepted that drag force is proportional to the square of the speed. The governing equation for drag incorporates factors such as velocity, surface area, and pressure, which plays a crucial role in both lift and drag for aircraft. Understanding the relationship between velocity and pressure is key to grasping how drag force operates. The discussion emphasizes the importance of these variables in calculating drag. Overall, a deeper comprehension of these principles is essential for analyzing air drag effectively.

Is air drag proportional to the speed or the speed squared? What data did you gather to support your answer?

Can someone please provide me an explanation? Thx.

type "air drag" into google

or to narrow your focus try

"air drag +wikipedia"

There's a basic governing equation for drag involving velocity, surface area and a couple of other variables. I've posted it here before, but since we're not supposed to just give out answers I'm not sure if I'm allowed to or not. To give you a hint - pressure is what gives an aircraft its lift as well as what causes its drag. Drag, being a force, is pressure multiplied by the area it acts upon. So if you know how velocity relates to pressure, you can get an understanding of how it relates to the drag force.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
