Page 40 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Page 40 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Page 86 - ... g sin 0 parallel to the line of greatest slope on the plane, and therefore the trajectory will still be a parabola, whose dimensions will depend upon 0. Ex. A particle is projected from a given point with a given velocity, and moves on an inclined plane/ find the locus of the directrices of its path for different inclinations of the plane. It will be easily seen that when a particle moves on an inclined plane, the velocity at any point is equal to that which would have been acquired by sliding...
Page 44 - To every action there is always an equal and contrary reaction ; or the mutual actions of any two bodies are always equal and oppositely directed.

Page 14 - Hence the moment of the resultant is equal to the sum of the moments of the two components.
Page 70 - The straight line down which a particle will slide in the shortest time from a given point to a given circle in the same vertical plane, is the line joining the point to the upper or lower extremity of the vertical diameter, according as the point is within or without the circle.
Page 302 - B, 0, &c. for which e is given, are placed in a line ; A is projected with given velocity so as to impinge on B, B then impinges on C, and so on ; find the masses of the balls B, C, &c. in order that each of the balls A, B, C, &c.
Page 44 - From this it follows that the sum of the quantities of motion, parallel to any fixed direction, of the particles of any system influencing one another in any possible way, remains unchanged by their mutual action ; also that the sum of the moments of momentum of all the particles...
