    Undergrad Circular motion vertical force

    I see... Thanks for clearing that up guys! Makes perfect sense!

    Undergrad Circular motion vertical force

    Do you mean to say that even theoretically, you cannot have an object in uniform circular motion completely with the attached string completely horizontal?

    Undergrad Circular motion vertical force

    Hi everyone, If you have a horizontal circular motion (with gravity action on the object), what holds the object up in the horizontal plane? All vertical components of the tension go to zero when the angle with the vertical axis is 90°... Where am I going wrong? Thanks Ramana

    Undergrad Upward force on a object spinning on on string

    Ok... I understand... Thanks a lot guys... :D

    Undergrad Upward force on a object spinning on on string

    I believe there is some confusion... I am sorry if I wasn't clear. The situation is a uniform horizontal circular motion (parallel to a level ground). I was wondering why the plane of the circle stays at that level and does not drop, despite the obvious force of gravity 'pulling down' on the...

    Undergrad Upward force on a object spinning on on string

    I just realized something... Is it that as soon as the rotating plane tilts away from the horizontal, the vertical component "steps in" to ensure that the plane is set back?

    Undergrad Upward force on a object spinning on on string

    Thanks for the reply... What I was wondering was how a vertical component could exist for a horizontal force... Anything I'm missing here?

    Undergrad Upward force on a object spinning on on string

    Hi everyone, I was wondering what forces would counteract the force of gravity on an object which is spinning horizontally on a string. I realize its a component of the tension, but how does the force come about? Is this force also the reason that the object's plane of rotation rises when we...

    Graduate Do Photons Have Electromagnetic Properties That Cause Attraction?

    Hey TGlad, so let me get this straight (am still a high school physics student :P) The paths A . . B | . . | | . . | | . . | | . . | a . . b are the paths of normal photons in a stream of light, i.e. side by side. but it is possible to get the second path also? i.e. get path aB and bA? is that...

    Graduate Do Photons Have Electromagnetic Properties That Cause Attraction?

    Just wondering if there was any connection with electromagnetic waves and bending with magnetic fields...

    Graduate Do Photons Have Electromagnetic Properties That Cause Attraction?

    Is there any electromagnetic property of photons that make them attract towards each other?
