Centrifugal force, Centripetal effort, Bucket argument
Isaac Newton’s ‘bucket argument’ was designed to show that true rotational motion could be defined only with respect to absolute space and not with respect to surrounding macro bodies, whatsoever states of motion they have. Even if whole universe (surrounding a bucket of water on earth’s surface) rotates about it, water surface in bucket will remain flat, unless bucket itself has a true spin motion with respect to absolute reference. Further mathematical analysis pointed towards real action by imaginary ‘centrifugal force’. It is not logical for imaginary efforts to cause real action. Analysing actions of 3D matter-particles of water (in rotating bucket in universal medium) by additional work associated with them (instead of equilibrium of ‘forces’ on it) can give logical explanation of actions, without using imaginary ‘centrifugal force’. All conclusions expressed in this article are from the book, ‘MATTER (Re-examined)’ . For details, kindly refer to the same.
