Proyectiles De Aceleracion Constante

When a gamer is playing Angry Birds he must consider various elements in order to win the level. He must evaluate the angle of elevation of the bird, the force applied to the bird, the distance it should travel and the time that must go by before the bird hit the pigs. All of these elements are characteristic of projectile motion. This movement is in two dimensions and has a parabolic shape if air resistance is ignored and if g is constant. Galileo was the first person to explain projectile motion. He analyzes this motion by horizontal and vertical components separately. One prediction of Galileo Galilei was that an object projected horizontally will reach the ground in the same time as an object dropped vertically (Giancoli, 2005). When a particle like object is launched its velocity on its X axis never changes while its velocity on its Y axis does. This is because gravity affects the movement on the Y axis. A projectile is an object upon which the only force acting upon it is gravity. This means it will have a specific velocity, acceleration, and displacement on X axis and it will also have a specific velocity, acceleration, and displacement on the Y axis. We must clarify that in most cases the acceleration on the X axis will be equal to zero since the object will travel horizontally at a constant velocity because there is no force acting on the object that will make it change its velocity. On the other hand, the acceleration on the Y axis is always constant with a value of 9.8 m/s2 which accounts for the gravitational force. We must also notice that the object is hit with an angle. This can explain why our object experiments motion in two dimensions; so it is important to clarify that the initial velocity will be different for X and Y axis.

The goal of this experiment was to study the behavior of projectile motion. Projectile motion is the movement of an object in the air. A projectile launcher was used to shoot a small metal ball through two photogates that measured its initial speed and landed on a platform that measured the time it spent on the air. This exercise was repeated several times, shooting the ball with different angles and with different heights.

In projectiles you can calculate a lot of variables. You can calculate the high of the projectile, the initial velocity, the angle of the projectile, the biggest height, the final velocity, the scope and also to calculate how long the ball takes to get to the final position in x.
