Essay On Projectile Motion

In this term paper, I will be relating projectile motion to personal experiences, movies, TV show, and Previous knowledge. In the first Unit of class we talked about motion in one dimension, but in this unit we talked about motion two dimensional. One example of a two dimensional motion is projectile motion. Projectile motion is when an object has an initial force that is applied to it to begin its motion. After the object starts its motion there is no longer a force that is being applied. At this point in time The only two forces that are acting on the object the first one and that largest one is gravity. The second force is normally neglected, when doing a projectile calculation. This small force is air resistance and causes the object

You have to add a force to the ball that gets it to the quarterback, but not so much that the ball flies over his head. Also you have to have it to where the angle of force and velocity are at a point to where the ball goes straight to the quarterback without dropping any in the vertical direction. The ball needs to get back to him quickly so the play can develop faster. If the ball starts to drop at all it means that the ball is not fast enough. The angle is the biggest factor to where the ball goes. If the angle is too acute then it will land at the feet of the quarterback or even before that, but if the angle is too large then it will fly right over his head. So the goal in a good snap is to put enough force to the ball at an angle to where the ball is almost at a velocity of zero in the vertical

“In a large sense, however, the term when applied to firearms refer to the efforts toward creating a more effective, predictable, and longer bullet trajectory” (Projectile). All three of those improvements have to do with projectile motion calculations. If the bullet can slice through the air then there will be less air resistance, which is neglected in the calculation anyways. When the bullet just slices though it will improve its speed along with how far it will go. When you improve both of those variables then it will also improve the predictability of the bullet's path. “During the fourteenth century until 1500, muskets were hopelessly unreliable” (Projectile). This is because the bullet that was shot was just a ball, which couldn’t slice through the air. Due to the air resistance, the bullet would slow down quickly but also start to wobble in air. When the bullet slows down it won't penetrate like bullets today, which would mean that the bullet wouldn’t have enough force to exit the body. Also due to the wobbling of the bullet, it would miss the intended target more times than actually hitting it. Although the shape of the bullet has a huge impact the variables so does the barrel of the gun. The imperfections on the inside of the musket barrel and the bullet it would not fly straight. “When fired, they bounced erratically of the sides of the barrel, and this made their trajectory
