The conservation of energy shows that when the ball is shot straight up the initial potential energy is usually zero due to the ball’s energy being associated with motion. While the initial kinetic energy is defined by the equation KE= 1/2mv ^2. As the ball flies upward the kinetic energy decreases as it is being transformed into potential energy. At the maximum height the potential energy will equal to zero. In table one for the five trials of the different setting the average distance was calculated and used to determine the time of flight. Once the time of flight was found the initial velocity was calculated. The initial velocity of table one was used to determine the time of flight for the initial launch angle 45. Once the time was found
