Have Fun with a Web-Based Asteroid Impact Simulator
Ready to have some fun while learning some physics? Try the new Earth Impact Effects simulator. This news release from the University of Arizona (UA) tells us more about this simulator of a collision between an asteroid and the Earth. You enter several parameters, such as the speed, the size or the density of the asteroid. And bingo! The program tells you the crater size or the seismic magnitude of the impact.

As UA says, if dinosaurs have had this program 65 million years ago, they would have known that the Chicxulub impact generated a seismic shaking of magnitude 10.2 on the Richter scale. This overview contains more details about the program.
