You are both wrong. Air resistance increases quadratically with speed, not cubically. And you mixed up polynomial with exponential. Quadratic: x^2 Cubic: x^3

Quadratic: x^2
Cubic: x^3
Polynomial (eg. 3rd degree): a + b x + c x^2 + d x^3
Exponential: e^x
- sokoloff 5y agoDrag force rises quadratically with speed. Power is force dot velocity; in this case force and velocity are in the same direction, so dot product becomes simple mulitiplication making drag power (exertion, formally: work per unit time) cubic with speed.
- newaccount74 5y agoOh, you are right! Sorry.
- antisthenes 5y agoI'm not wrong, because I wasn't commenting on the power of the exponent. But thanks for being a typical HN.
