Name: Section: Grade 9 Science: PHET Projectile-motion Lab Link: https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html Objective: • Investigate the relationship between the projection angle and the height and range of the projectile Instructions: 1) Set the height of the cannon to 0 m. 2) Set speed to 15m/s. The cannon angle can be changed by clicking and dragging on the end of the cannon. (The default projectile is a pumpkin, but you may change it to any other object in the dropdown menu on the upper right corner of the screen.) 3) Measure the range and height for each angle listed below. 4) Use the tool to determine the projectile's time, range, and height. Range Height = Angle 25° 30° 35° 40° 45° 50° 55° 60° 65° Range Height Time Answer these questions: 1. What happened to the range of the projectile as the angle increased from 25°-45°? 2. What happened to the range of the projectile as the angle increased from 45°-65°? 3. Compare the range of the object at 25° and 65°. 4. What happened to the height of the projectile as the angle increased from 25°-65°? 5. What angle achieved the maximum distance? 6. How do the concepts of range and height in projectile motion relate to real-world scenarios? Conclusion about the relationship between the projection angle and the height and range of the projectile:
