Escape Velocity and Gravitational Force

  1. Nov 27, 2014 #1
    Hey Guys!
    I've been doing a few equations in regards to planetary escape velocity and gravitational force.
    The below links have the escape velocity of listed planet on the left side of the board, the gravitational force between the Sun and given planet on the right side. In the middle of the board I provide the data i used within the equations. I only did 3 planets but i plan on practicing more using the other 5 planets and I may even include Pluto. I have confirmed all the escape velocities using NASA's data tables but I cant find any sources to check my work on the gravitational force between said planet and the sun. So, I was wondering if some generous person out there could check my work.
    Here are the links: (You can click on the picture to enlarge it)

    All equations are listed on the board, all math was calculated through Wolframalpha.com
    Thanks everyone!

    Whoa! I had no idea Wolframalpha could do that! Thank you!

    No worries!

    It constantly surprises me what it can do. Of course, it's always best to calculate by hand when you're learning a concept, but it's a very useful check!
