To simplify, assume the cow is spherical

Well technically you can neglect anything you want.

So much friction right now.

Man, physics is stupid difficult to learn without spherical cows and frictionless surfaces.

Hell, astrophysics has so much “eh we can ignore this number because it’s so tiny compared to a black hole.”

And don’t forget about Quantum. There’s a whole time-dependent AND time-independent wave equation.

Instructions unclear. Forgot about quantum physics, and now my dick is phasing in and out of existence.

Isn’t air resistance friction?

olafurp@lemmy.world on 24 Jan 18:36 collapse

Not entirely. You get a lot of air resistance from vortex shredding which pulls the object back because of turbulent air flow at high speeds behind the object. You also have collision with air molecules when they are compressed in front of the object.

Friction on the other hand is more dominant when pushing an object along a surface.

To be fair, a spherical cow is worth its weight in money

He was a helicopter gunner / pilot… Air resistance really matters!!
