Ankit Patel Prof. Hardy Partners: Jon, Shawn, 9-28-10 Experiment 3: Projectile Motion Objective : The objective of this experiment was to study the kinematics of a projectile in the gravitational field to understand horizontal range, maximum height, time of flight, and the trajectory of the projectile. Discussion : In the experiment, motion is determined by an initial velocity and a launch angle. A max horizontal velocity was used as a control to find out the range, max height and time of flight of the ball bearing. The main idea here was to fire the ball at different angles and calculate the values of each trajectory. The results showed that the max range a projectile can have at 45 degrees. This makes sense because of the angle maximizes its horizontal axis in terms of distance. For maximum height, an angle of 80 degrees was showed to obtain maximum height. In theory, 90 degrees would be the optimal angle for maximum height because there is no motion in the horizontal direction, thus giving a maximum height of the ball. Time of flight was pretty straight forward. If the angle of the launcher increased, the
