Cruz (School of Civil, Environmental and Geological Engineering, Mapúa Institute of Technology, Philippines) Introduction Projectile Motion is a different kind of motion because it still moves along a straight line but because of gravity it falls back again to earth after being released into air. Projectile Motion usually travels along a parabolic path or trajectory. There are many applications of projectile motion including the release of canons, throwing objects and even long jump from one place to another. The experiment will try to explain principles regarding projectile motion like the range of projectile, the angle of projectile and the highest point of projectile. This experiment aims to explain relationship of angle, range, and maximum height to the projectile being released. Results and Discussion In this experiment, projectile motion, we explored and defined projectile motion, first we must consider the elements and the factors that will contribute and will affect to the entirety of the concept of this 2D case. In the experiment, the motion of an object within the effect of the gravity is completely determined by acceleration . of the gravity. The speed of the launch, and angle of the launcher that provide friction in air is insignificant. The motion of vertical and of the horizontal can be pull apart and is outlined by the general mo tion equation for the . . constant acceleration. The initi al vector components of the velocity are used in the equations. . . . . . . . . . . . . . Figure 1. Preparing the launcher Figure 2. Loading the launcher Figure 3.

It is special because, while the projectile is airborne, the only external force on it is that due to gravity. Gravity is the only considered external force acting on it while an object is airborne. As fired at an angle, it is influenced by its horizontal inertia and vertical gravity. In the experiment, it shows that the larger the launch angles, the shorter the range that we get though it has a higher maximum vertical distance. We calculate the difference in the percentage from initial velocity where the angle we use is at 0°. Our data also displayed that the larger angle would produce a lesser difference in percentage which means that the approach is closer to a quadrantile angle, where the angles forms a line. The bottom line part is in the ground to ground motion projectile, the one thing that we must considered is to be able to successfully fire the metal ball to the target, is the angle of the launch, since as what we got in the experiment, the greater the launch angle, the higher the maximum vertical distance and a shorter range.
