Your gut instinct is correct. That's because, in this example, you are scaling the mass of the object (giving it huge inertia), while keeping its size constant, hence leaving unchanged the magnitude of the forces exerted on it by air friction. As a very rough estimation, the work performed by the forces that lead to a change in angle will be identical. But due to the larger inertia, that work will result in a much smaller change in orientation.
What would your gut tell you if now that same steel football rotating at 1M rpm was also propelled at an initial speed of mach 1.5, yielding 3 or 4 minutes of flight?
- leetcrew 4y agomy gut tells me I really don't want to be a wide receiver in this game.
- aidenn0 4y agoI think any part of your body that touches that football will tell you that...
- amelius 4y agoI think that mass does not even matter, i.e. even with the same mass, with 1M rpm rotation, and propelled at the original (slow, subsonic) speed, the football would have enough angular momentum to keep its orientation, regardless of trajectory or air.
