bullet fired

The Mythbusters first test to find out if a bullet fired or a bullet dropped hits the ground first, then examine the myth that a sufficient punch can knock a person out of their socks. This classic experiment is typically described in all physics textbooks, when the independent nature of the X and Y axis is discussed. Topics of importance include independent axis, gravitational pull, velocity, drop height, engineering practices, valid vs. invalid results, uncontrolled variables, inertia and mass relationships, potential energy and kinetic energy, controlled variables, friction, and pressure waves.
