...will be nine. The product of a number multiplied by itself is called its square : thus, you see, " the resistance of the air increases as the square of the velocity." It is owing to the resistance of the air increasing so much more rapidly than the velocity of a falling... | |

...moment, and thus forces the body downward faster and faster. This illustration is not perfect, because the resistance of the air increases as the square of the velocity of the body, and, if the body continues long in falling, will at last produce uniform motion. A constant... | |

...following Table ; — The difference between the two velocities increases with the head. It should be so, since the cau.se of this difference, the resistance...square of the velocity, and consequently nearly as the head.

...4 to 6 pounds to keep it moving slowly. As the speed increases, a greater force is necessary, since the resistance of the air increases as the square of the velocity. That is, if a train is made to move twice as fast, the resistance becomes 2x2 (or 4) times as great;... | |

...globes are represented by the squares of these numbers, viz. 1, 4, 9, 16. From this he concluded that the resistance of the air increases as the square of the velocity. Recent experiments have shown that Newton's law is not absolutely accurate. Up B 2 to 10 metres per... | |
