Query on an object moving in a 2D plane

  1. Sep 14, 2007 #1
    An object is at a known point in a 2D plane, travelling at a known speed in a known direction

    In the plane are other objects with known mass and location

    With this information, how do you work out where the object will be located one second later?

    What forces act on the object?

    Gravitational attraction from the other bodies in the plane

    Unless it's a simple configuration of masses, you'll probably have to use numerical methods to solve for the acceleration and position as a function of time.

    I'll have to show my ignorance, what is meant by a simple configuration of masses?

    By that I just meant a configuration simple enough to solve analytically, without the need for numerical methods.

    That would typically not be the case

    How would I go about solving for the acceleration and position as a function of time?
