When someone ends up comitting a crime, sometimes a gun is involved. For example last week on a feild trip, i was able to sit into a trial of someone who commited a murder. During that trial they brought up the evidence that the lady was killed with a gun. When they brought up someone to testify, he was a gun expert. He started talking about how the gun must have been shot and how projectiles are involved. I thought it was cool how someone started to bring physics into trying to solve a murder. Also he started talking about the angle that they must have shot the gun at and how it would make the damage to the person differ. Overall i thought it was very interseting how they used physics in order to figure out if that gun really was the weapon that killed the lady.
