    In a question, I was told that the horizontal component of tension on a bung provides the centripetal force.

    In the g484 June 2014 paper, I was told that the aeroplane in Q2 has a variable force P whose horizontal component provides the centripetal acceleration.

    So which is right?
    Does the horizontal component provide the centripetal force or acceleration?!

    Please help.

    nwmyname Any object that moves in circular motion is acted on by a resultant force that always acts towards the centre of the circle. The resultant force is the centripetal force and so causes centripetal acceleration.
    So I guess you could say that the horizontal component provides both.
