Homework Help: Newtons Law's

  1. Oct 7, 2005 #1
    I'm not exactly sure how to go about this problem, well how to explain it. I've looked at a number of websites as well as other resources and I can't figure it out. If someone can assist me it would be greatly appreciated. Thank you! :smile:

    When combinding the equations for Newton's Law of Universal Gravitation and the Second Law of motion to make a mathematical statement, What is the significance of this mathematical manipulation?

    If you don't know what "F" is in Newton's 2.law, you can't make a lot of predictions about objects' trajectories, can you?

    Now, ask yourself, what is it that Newton's law of universal gravitation tells you, and how can you use this to generate predictions?
