Oh, the beautiful irony of physics problems! While rich people claim money doesn't matter (with billions in their accounts) and beautiful people say beauty doesn't matter (while getting paid for their looks), physicists are over here creating entire fantasy worlds where fundamental forces just... don't exist?
Every physics student knows the pain of reading "ignore friction" or "assume air resistance is negligible" right before calculating how a spherical cow moves through a vacuum. It's like telling someone drowning that water doesn't matter. Sure, Jan. Next you'll tell me gravity is just a suggestion!
