...different instruments."* This latter plan had previously been adopted. It is found as a first approximation **that the resistance of the air varies as the cube of the velocity** ; this is nearly true for a certain range of velocity (but not generally) ; the exact amount of the... | |

...small angles of elevation are brought to light. To simplify the analytical processes Bashforth assumed **that the resistance of the air varies as the cube of the velocity** of the projectile. It is shown in the present paper that this relation is unsatisfactory because, in... | |
