Horizontal and Vertical Motion
A bullet is fired from a gun held parallel to the ground. At the exact same moment, a second bullet is dropped from the same height as the gun. Which bullet hits the ground first?
The answer to this classic conundrum is not at all intuitive. It depends on a fundamental fact of physics: vertical and horizontal motion are completely independent of one another. While we won’t be firing any guns in this investigation, we will use some everyday objects to demonstrate a basic law of motion that applies to everything from a home run baseball to a rocket launch.
