Bernardino, Rene TA: Projectile Motion March 4 2024 Introduction This experiment involves launching a steel ball from a horizontal cannon and then repeating the launch with the cannon at an inclined angle. The objective is to predict the landing point of the ball from the launch point, considering the influence of gravity. Kinematic equations are employed to determine the missing values and forecast the ball's trajectory. To predict the landing point accurately, the experiment involves averaging the values obtained from six horizontal launches to determine the initial horizontal velocity (Vox) and horizontal displacement (Xtheo). This Vox value is then used to calculate the predicted horizontal velocity for the inclined launch. The actual horizontal displacement is determined by averaging the results from six inclined launches. Comparing the predicted horizontal displacement (Xtheo) based on the calculated initial horizontal velocity to the actual horizontal displacement from the inclined launches shows a close similarity between the predicted and actual values. This demonstrates the effectiveness of kinematic equations in predicting projectile motion. Results

This allows for the determination of the relationship between velocity, gravitational acceleration, and the distance traveled. Understanding this relationship at a horizontal level provides valuable insights that can be applied to predict the distance traveled when the spring is at an angled position. The predicted launch result (Xtheo) was 3.15 meters, while the actual launch measurement (Xincl) was 3.34 meters. The uncertainty associated with this experiment was 0.05 meters due to the measurements not being analog with a 9.5% difference between the prediction and actual launch measurements. Discussions The results of this experiment showed that the steel ball traveled 2.53 meters when launched horizontally and 3.34 meters when launched at a 30-degree angle. Despite the gravitational pull toward the Earth remaining a constant value of -9.8 m/s², the distance traveled by the ball varied depending on the launch angle.
