The development of cannons was an important part of wartime history and, surprisingly, of physics. The very movement of a cannonball is so similar to the movement of a projectile that it is not too difficult to understand that there is a connection between the two. Projectile motion, which is part of mechanics, is the movement of an object in a two-dimensional world. Since a cannon moves in these two dimensions, forming a similar curve, they are an excellent example used in the application of projectile motion concepts. Discovering one of the greatest practical uses of physics is to identify how physics contributed to the development of the canon using examples, relate it to at least two factors, and further answer a question of research that we asked ourselves: “To what extent is physics applied to the development of cannons? ”Physics has made a considerable contribution to the development of cannons. It is as early as 1646 that there are documents showing that physics was used to improve the cannon. The most common uses of cannons were in acts of war and the first time anyone applied physics to this concept was during the Siege of Worchester. Nathan Nye, author of the book "The Art of Gunnery", applied various forms of triangulation, arithmetic and theoretical mathematics to win this battle using cannons. Of course, he was a key figure who contributed to the development of the canons (Nye). One of the first scientists to formulate his own theories about the motion of a cannonball was Aristotle. He believed that if a cannon was fired, the vertical motion would be constant in proportion to the weight of the object ("Aristotle versus Galileo"). He also believed that the projectiles traveled up and out in a straight line until they "ran out of gas" and then fell straight down. This...... middle of paper......gives the military advantage to their respective side. This seemingly endless search for that elusive, perfect projectile continued even after the end of the Civil War (Melton). The development of the canon had a great influence on society through various factors. He discussed physical theories on movement and more particularly on the movement of projectiles. He described the factors of this movement such as the acceleration of gravity and horizontal and vertical velocities. As we have seen, this has had significant economic and ethical impacts on society. These factors relate to how physics contributed to the development of the cannon and provided general insight into the physics behind the cannons. The data collected is sufficient to conclude by stating that physics largely contributed to the development of the cannon..
