Going uphill with no friction (vacuum)

  1. Apr 13, 2012 #1
    Going uphill with no friction, think maglev, what forces would the mass/vehicle only have to overcome its weight... and gravity? I used the 'search' function but yielded no results.

    Please feel free to discuss or to simply put me in the right direction.

    Just to put things in context, I am trying to get a vehicle (similar to a maglev) down from a certain elevation and back up.

    I apologize if it's an obvious question, shame on linguists for their lack of physics.

    If the slope angle is A, and the maglev is exerting a force at right angles to the slope sufficient to prevent its landing, the additional force you need is one up the hill. If the weight of the object is W, the force you need to exceed is W.sin(A).
