Newton's 3rd Law

This past summer, I visited Vietnam. We got to do a lot of new things but one of the really cool activities we did was visiting the Cu Chi Tunnels, a former military base during the Vietnam War. The tunnels now serve as a major tourist attraction where people can learn about the underground tunnels, built by the Viet Cong, buy war memorabilia including zippo lighters and dog tags of fallen American soldiers and even shoot various types of guns at a shooting range. Despite the fact that I look extremely weird in the picture, this is a picture of me shooting an AK 47. Newtons third law states that for every action, there is an equal and opposite reaction. When I shot the gun, there was a strong kick or recoil. There was a worker assisting people and telling them where to stand and gun was mounted on the wall to prevent any serious injuries caused by the recoil. According to Newton's third law of motion, the force that I felt when the gun recoiled was equal to the force exerted on the bullet. The reason the bullet accelerates more than the gun however, is because the mass of the bullet is so much smaller. The greater mass of the gun on the other hand, results in a much lesser acceleration than the bullet.
