FISIKA DALAM PERMAINAN BOLA VOLI: PENGARUH BESAR SUDUT TERHADAP SERVIS BAWAH DITINJAU DARI GERAK PARABOLA

Abstract

_{Parabolic motion is the curved motion of an object whose trajectory is a}

_{parabola. In objects that experience parabolic motion, objects will experience the}

_{farthest distance and the highest point. The farthest distance traveled by an object in}

_{motion with a parabolic trajectory is influenced by the elevation angle formed, this is}

_{because the velocity in the direction of the x-axis and the velocity in the direction of}

_{the y-axis are affected by the magnitude of the angle of elevation formed. The purpose}

_{of this study is to analyze the motion of the parabola on the volleyball serve with a}

_{variety of different angles so that volleyball players can find out the ideal angle for}

_{the under serve so that the ball can fall on target and over the net. This research is}

_{using experimental method. The results of a good and ideal angle when serving under}

_{a volleyball so that the ball falls on target and crosses the net using an initial angle of}

_{600, a falling angle of 250, and with a speed of 11.2 m/s which is analyzed using a}

_tracker.
