Airsoft Gun Physics

This weekend, I decided to shoot my airsoft gun. Though I was'nt playing against anyone else, I just felt like practicing hitting targets. Like Adrian, my airsoft gun is an aeg (airsoft electric gun) but his is cooler. Even though I have a m4 and he has a G3SAS, our guns use the same principles of physics to fire bb's. When you pull the trigger, the gears in your gun push a coiled spring as far back as it can go and a bb is pushed up into the barrel from your clip by a hop-up system. The spring is then released, propelling the bb at a very fast speed from your barrel at your target. The speed is measured in feet per second (fps). In the end, the velocity of your bb as it comes out of the barrel depends on many factors such as: the quality of your battery, spring, or gearbox, or the size, weight, and type of your bb's.
