...velocities and directions of projection. In Art. 193 it has been proved that the motion relative to the centre of gravity is the same as if the centre of gravity were a fixed point. Hence we must apply to each body a velocity equal and opposite to that of the common centre of gravity,... | |

...independently of any initial rotatory movement, the pendulum in the course of its oscillations will acquire a motion of rotation about the axis passing through the centre of gravity and the point of suspension. It is shown further that this rotatory motion is not of an oscillatory... | |

...point of the fluid mass. 6. The motion of rotation of a rigid system acted on by any forces, about its centre of gravity, is the same as if the centre of gravity were fixed, and the same forces acted. A heavy beam moves about a horizontal axis passing through one extremity... | |

...and taken it as the origin of moments. Hence The motion of a body, acted on by any forces, about its centre of gravity is the same as if the centre of gravity were fixed and the same forces acted on the body. That is, from (4) the motion of translation of the centre... | |
