...found, whatever may be the size or shape of a body, and of whatever material it may be made. This point is called the centre of gravity. The centre of gravity of a body, then, is a point such that the force of gravity acting upon the part of the body on one side of this... | |

...regarded as such without any sensible error. The centre of these parallel forces is what is termed the centre of gravity. The centre of gravity of a body is, then, the point through which, in every position of the body, will pass the resultant of all the forces which, in consequence of gravity,... | |

...and hence in all positions of the body the resultant of the several forces will pass through o. 52. Gravity is the force which attracts every particle...in consequence of gravity, act upon its particles. 53. It follows from the definition, that if the centre of gravity of a body be fixed, the body will... | |
