  • The Ring of Fire: a Cheap Steel Wool Pyrotechnic Display

    You need to contact Webster and other dictionary sources as well as publishers of many physics books. While I agree centripetal motion restrains the object from flying out tangentially if the cord holding it broke it will fly. That so called 'tendency' , interesting new app there could be called potential energy just waiting to become kinetic. Perhaps Kinetic is not a word like centrifugal??

    This is reminescent of 'hole flow' for semiconductors vs 'electron flow'. Such did confuse things in the 60's. Though I understood both approaches I also understood that the movement of a proton is much less than that of an electron attracted to it (1870 times smaller if I remember right). The same thing could have been identified in realistic electron flow more easily though some pressed the point on hole flow.

    A force indeed is a vector, an object or particle like light aimed at a specific direction. In physics design of lets say a bridge there are stress vectors/forces calculated in the design so that it can handle the load proposed and can remain standing and strong. Force is the most basic in design parameters for physical things. Though it can handle the stress if something flew apart it would have a lot of momentum probably - force at a speed.The design of a bridge is to handle centripetal forces together -restrained from collapsing or breaking apart, but the same bridge has great centrifugal force when it does. Force still is potential energy and force released is kinetic energy.To me as per education I was taught centrifugal force - restrained by centripetal force or in motion as a f...see more »A force indeed is a vector, an object or particle like light aimed at a specific direction.

    Since science has eliminated the word centrifugal it needs to replace it with inertial and centrifuges need to be called inertiafuges?
