Page 184 - 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 185 - 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 15 - If two forces acting at a point be represented in magnitude and direction by the...
