Crater formation is a complex process, and it isn't obvious that one would be able to learn much about it from a small tabletop experiment. However, by making a few assumptions about what happens to the kinetic energy of an impactor after it strikes a surface and by applying dimensional analysis, we can come up with a simple model for how crater diameter scales with the kinetic energy of the impactor.$K=\frac{1}{2}mv^2$$m$$v$$M$$V$$d^3$$M \propto V \pr… text/html 2023-07-12T11:47:30+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.physlab-wiki.com/phylabs/lab_courses/smart/cratering?rev=1689176850&do=diff Cratering (SMART) Welcome to the laboratory component of the Science Mathematics And Research Training program here at the University of Chicago. In this laboratory exercise you will conduct an experimental investigation to determine how the size of an impact crater depends on the energy of the projectile which created it. Over the course of the lab you will gain experience in the process of conducting Scientific investigation into a physically complex phenomena including;$K=\frac{1}{2}mv^2$$… text/html 2025-07-10T14:11:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.physlab-wiki.com/phylabs/lab_courses/smart/smart-instructor-info?rev=1752171072&do=diff Home area for Cheng Chin's SMART program. This space is for the one day version of the Cratering lab which is used for Cheng's summer SMART outreach program. Outline * Motivation : Describe cratering and pose question of how would you estimate the yield of a nuclear bomb, or the energy of an asteroid that made a crater on earth or the moon? text/html 2025-07-07T12:10:58+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.physlab-wiki.com/phylabs/lab_courses/smart/start?rev=1751904658&do=diff Cratering (S.M.A.R.T.)
