title: Shoot a Target Objective: You will predict a horizontal range of cannon from various heights. Apparatus: Go to https://phet.colorado.edu/en/simulations/projectile-motion Background Theory: In a projectile motion, an object moves under the influence of gravity only. The motion in the x-axis and y-axis are independent of each other assuming there is no air friction. While the object moves a vertical distance, it also moves horizontal distance. Therefore, the kinematics equations of motion are sufficient to analyze the projectile motion
