  • In fact you feel a "centrifugal" force (fake force), or center escaping force, which is due to the constant changing of direction around a circle (now that objects tend to follow linear paths of motion). Centripetal force is what keeps pulling on you so you follow a circular path instead.

  • @wolterh6 why is it a fake force? isn't that the force make us standing on earth

  • @jj987987987 There is no actual force pulling a body rotating body away from its axis. The feeling of being pulled away is created by the circular motion, which according to Newton's First Law, is unnatural. The force making us stand on Earth is the force of gravity, which depends solely on the mass of the attracting bodies.

  • @jj987987987 The 'Force' of Centripetal Acceleration is very real. This force is always perpendicular to the axis of rotation. "Centrifugal Force" is the 'imaginary' force resultant from the former 'Real' force. Engineers use it as a convenient component of their calculations. Another example that sounds like the same thing, is "Weight" and "Mass". Weight can change, but Mass remains the same.... Crash a "Moon-Buggy" into a moon rock, and the 'Mass' NOT the 'Weight' will do the damage!;?D)

  • If you pause like at 1:21 you can see her shorts got stuck to the pole lol

  • Ehh what the video was about? I remember only a nice girl and her legs :)

  • ...what would it be like if you spun something around a center in zero g and micro g respectively? since the 3rd varible is space instead of a down direction if you get me.

  • Great couple!

  • I thought your deffinition of all this was that centrifugal force is the opposing result of centrapedial forces pushing outward, which is pure bull, or am I wrong and you don't even really know yourself?

    centrafugal force does exist and no amount of arguing will change my mind about the freaking subject, gyro's, spin balancing upright using inward forces, and balls on strings fly tangent not outward YOU ARE ALL WRONG...

    and stop killing eachother while your at it...

  • While there is centripetal force, there is centrifugal also, according to Newton's law of action and reaction.

    When you cut string, you lose centripetal AND centrifugal forces. Inertia produces centrifugal force WHILE centripetal exists, not afterwards.

  • Centrifugal force is what you have demonstrated so you must have gotten an F in your class. Centripetal force is inward directed, not outward like the examples you provided. The diagrams were right, but the examples are way wrong!

  • centrifugal force is fictitious...the inertia combined with the inward centripetal force causes an object to...well...push outward...but its because of the combination of these forces...not an outward pointing force......

    if you spun a tennis ball around on a string and instantly cut the string...would it fly straight outwards? no it wouldn't....if the centrifugal force was real it would...but its not

  • watch?v=O6yJG_fnJRc

    this vid fixes your confusion...

  • While centrifugal force is referred to as fictitious, that doesn't mean it isn't real - the word has a technical definition.

    Also, how is Newton's third law so easily forgotten? Equal and opposite reaction! If centripetal force exists, so must something to react against it.

    Finally, your example is fallacious. If gravity stopped working, would the normal force shoot you into space? Of course not.

    Centrifugal force exists. Any claim otherwise is an exercise in frivolity.

  • @rayzorium nice critique, but if gravity stopped working, there wouldn't be a normal force in the first place. Centrifugal force doesn't exist. Think of the instantaneous acceleration of the people. This "centrifugal force" is just inertia reacting to the acceleration caused by the change in direction. Oh, and as for this "newton's third law" argument. The equal and opposite force you're looking for is also in their arms. They are pulling on the equipment, the equipment is pulling on them.

  • @numair23 That was actually my point. I was originally responding to spike0804; what I said should make more sense upon reading his comment.

    In any case, you can't simply say that something doesn't exist just because it can be called something else. For example, nobody goes around saying that the Coriolis effect doesn't exist just because inertia is also responsible for it. That's what I meant when I said it was frivolous. It's as real as inertia itself; people just don't like the name.

  • Good music track from The Pillows!

  • A better example would be orbiting planets, or the valance electrons of an atom. You were demonstrating centrifugal force. My Electrical instructor made the same mistake.

  • C-E-N-T-R-I-F-U-G-A-L

  • they have sex, it seams:D

  • Centripital force does not exist nubsauce... its just a theory to explain a phenomenon

  • Wrong centrifugal foce does not exist (excuse my spelling i am dislexic) its a mixture of unbalanced cetrepedal force, :)

    and as it can be calculated accuratly, its not a phenomenon (technically)=p

    alec

  • You are just lazy. :)

  • ok the explanation was good.

    But the Demonstration was not and the reason is that after the circular motion of both of you guys, you both were thrown OUT wards, NOT inward, which contradicts with the Centripetal Force (Center Seeking Force)

    Over All = Great Job.. :)

  • @AfgSpartacus: While holding on the bodies are subject to both forces, which balance each other exactly, as the 3rd law states. If that were not true, their orbit would not be circular. When they let go both forces disappear simultaneously; now the bodies are subject to no force except gravity, so they fly off at a tangent to their original path.

  • =O lol

  • interesting
