Hi(adsbygoogle = window.adsbygoogle || []).push({});

Basically, I am doing an A level project, in which I am investigating impact craters.

I am modeling this by dropping ball bearings into sand, and measuring the depth and width of the resulting crater.

However, my results are quite unclear, and I would really appreciate some guidance on the trends that would be expected.

My main question : would you expect there to be a constant width-depth ratio as the height of the ball drop increases?

Would there be a constant ratio as the weight/radius of the ball increases?

Thanks, any help is much appreciated.
