...tends in the case shown to separate these two bodies. NEWTON'S LAWS. 1st Law. "Every body continues in its state of rest or uniform motion in a straight line except in so far as it may be compelled by force to change that state." 2d Law. "Change of motion is proportional...

...Galileo's law of inertia which states that a body sufficiently far removed from all other bodies continues in its state of rest or uniform motion in a straight line. A Galilean system is one, the state of motion of which is such that the law of inertia holds for it....

...accepted as the foundation of mechanics. Newton' n laws aa expressed by him are: 1. Kvery body continues in its state of rest or uniform motion in a straight line, except in so far as it may be compelled by force to change that state 2. Ohange of motion is proportional...

...They deal with the relation between force and motion. 135. Newton's First Law. Every body continues in its state of rest or uniform motion in a straight line unless it is compelled by some external force to change that state. This law is really a statement...

...direction of their motion (see gyrocompass opposite p. 223). FOECE AND MOTION Every body continues in its state of rest or uniform motion in a straight line unless impelled by external force to change that state. This property, which all matter possesses,...

...in the form of three laws, which are given as originally stated by Newton : I. Every body continues in its state of rest, or uniform motion in a straight line, except in so far as it may be compelled by force to change that state. II. Change of motion is proportional...

...earth? " Newton answered with the statement of his First Law of Motion. Every body tends to continue in its state of rest or uniform motion in a straight line, unless acted upon by an outside force. He considered the moon as having a motion of its own, which,...

...law of motion states that a body which is sufficiently far removed from all other bodies continues in its state of rest or uniform motion in a straight line. This holds very approximately for the fixed stars. If, however, we refer the motion of the stars to...

...about which judgment is passed. I may judge that this leaf is green and that "every body continues in its state of rest or uniform motion in a straight line unless impelled by external force to change that state"; also that parts of the leaf are green and...

...Motion. — The science of mechanics rests primarily upon three statements : I. Every particle continues in its state of rest or uniform motion in a straight line unless it is acted upon by some exterior force. II. The rate of change of momentum of a particle is...
