Perpendicular force from cross product

  1. Apr 21, 2014 #1
    Cross product is used to find the perpendicular vector of two vectors. If there is any two vectors in a plane then there is always a perpendicular vector to both of them.

    So in circular motion if the motion is horizontal then is there a perpendicular force to the object in circular motion?

    Perpendicular to what?
    The centripetal force is perpendicular to the velocity vector, if the motion is uniform.

    That's a confused question. You start by talking about cross product and then end up asking a question about circular motion without ever linking one thing to the other.

    Maybe he is asking if there are two vectors(Velocity and Force) in circular motion,what is the perpendicular vector to both of them?

    May be, may be not. How is one supposed to tell when the question does not give a clue? It always amazes me how often people can't take the time and put the effort to write a post that makes sense.
