What is the practical use of centripetal motion?
Ever used a pushbike? addition Exactly, Legs on a push bike; reciprocating pistons in engines; heated vapor driven turbines in jet engines.Note in all the examples centripetal motion is a motion, not a force, Isac Newton's human error, he said it was a force, when in reality it is a motion, requiring a force to cause it.A dog on a chain experiences centripetal motion, when it charges out and reaches the end of the chain. but it was the dog, that provided the energey. In a solid universe all motion is a reaction to force, without force nothing can moves, and or if moving stop moving!So there is only one force powerful enough to spin the world, and the planets, if man's theories of multi millions of years of the universes exsitence is TRUTH, and not just thought to be. There has to be a force in The Cosmos, that humans have never comprehended, so they named it God: claimed it to be in their image; thought up actions, and ceramonies of praise, and glorification, to appease it; created beliefs, and theories to explain the actions of this deity! The scriptures, tell it over, and over; Man has never Known the TRUTH!
