Airsoft guns demonstrate many basic concepts of physics and wouldn't be able to work the way they do without physics. These guns include velocity, kinetic energy, impact energy, length, diameter and more. The first factor that comes to mind when range is involved includes velocity. Velocity with airsoft guns determines how powerful the gun is and how much damage it could potentially do. This shows how energy ad power is also involved with airsoft guns. Many types of physics equations can be used to determine factors such as power, energy, velocity etc. Next, the diameter of the small BB's determines how far and fast they will travel after leaving the gun. All in all, each characteristic incorporated with BB guns demonstrates the characteristics of physics.
