' Record your measurements in the following table: \f' Answer the Testable Question. ' Write a statement that describes the relationship between vertical displacement and theoretical time of ight. 0 Write a statement that describes the relationship between the vertical displacement and theoretical range. ' What were your Independent and dependant variables of this simulation? 0 How can you manipulate other variables to study the projectile motion? 1) Go to the following website https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion en.html Projectile Motion Vectors Drag Lab Intro 2) Choose the tab that says Lab Projectile Motion Intro Vectors Drag Lab3) Set your initial values Initial Values Height: 0 m Angle: 80" Speed: 18 m/s Choose type of Cannonball Mass projectile Diameter 0.18 m 0.1 Gravity 9.81 m/s' Air Resistance Altitude om Rotate to choose Drag Coefficient 0.47 10 m 80 the angle 15.0 m Initial Speed 18 m/s Choose initial Normal Slow velocity 4) Keep your initial values fixed all the time. 5) Start changing the height of the cannon by dragging it upwards 6) Press the red button in the bottom middle of the screen to shoot the projectile 7) Measure the range and the time of flight by dragging the measuring tool at the top right of the screen
