The first of these Laws is : — Every body continues in its state of rest or of uniform motion in a straight line, except in so...as it is compelled by forces to change that state. In other words, any change whether in the direction or in the rate of motion of a body is attributed...

...can still assert the laws of motion in the following form:— Law I. The centre of mass of the system perseveres in its state of rest, or of uniform motion in a straight line, except in so far as it is made to change that state by forces acting on the system from without. Law II. The change of momentum...
