In the learned discourse on this forum, Newton's SECOND LAW OF MOTION has been mentioned.
I now share an event involving Newton's FIRST LAW OF MOTION . . . avert your eyes NOW, gentle readers, if you wish to avoid the narrative!
On another forum, an inmate rationalized the KLR650's modest power output to some extent by claiming, "The doohickey (counterbalancer system) alone uses TWO HORSEPOWER!"
I disagreed, invoking Newton's FIRST LAW OF MOTION:
An object at rest will remain at rest unless acted on by an external force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.
(Or, words to that general effect.)
I reasoned (?), if Mr. Newton isn't FUNNING us, after the balancer system (shafts/weights/chain/etc.) is in MOTION, the only power used sustaining the motion is that used to overcome bearing friction, chain friction, and air resistance. I doubted this compensatory power expended by the balancer system approached anything near two horsepower.
I was branded a heretic; accused of creating a fantasy, "perpetual motion" machine; and pilloried by many unkind words from loyal supporters of the inmate who posted the two-horsepower budget operating the doohickey.
Still, I could think of no external forces acting upon the doohickey (balancer system) than those of bearing friction, chain friction, and air resistance. Thus, my heart and mind remained unchanged. If Mr. Newton withstood the criticism, so can I!
