    Hi everyone, it's my first post.

    I'm in need of some help. I decided to to my experiment on craters and realised there is not much to talk about.Perhaps I am wrong. Can someone direct me on what sort of stuff to include.

    I have the mass of the ball and distance dropped and use E = mgh to find out energy.I guess I could work out the velocity of each ball but not sure if that is relevant.
    I have recorded the depth and width of the crater and have already plotted graphs with error bars

    This may sound stupid, but am I supposed to relate this to how craters are formed on the moon?

    So I really need to 'beef' up this coursework as I am lacking content.

    Thanks for any help in advance.
