PART 3: Research question: C. What effect did have the launch angle on the horizontal distance the projectile travelled? Answer your hypothesis prior the experiment. My hypothesis is ... Experiment 2: Set height of cannon to 0 m Set speed to 15m/s. The cannon angle can be changed by clicking and dragging on the end of the cannon. Measure the horizontal distance (Range) for each angle listed below. Doubts: Recording: Angle versus Range Table 2. Projectile launch angle versus total horizontal range travelled at same height and initial speed. X axis Angle (degree) 25 30 35 40 45 50 55 Y axis Horizontal (range) Distance (m) 60 65 Insert here (below) a screen shot of all the trajectories for each launch angle: 2-DIMENSION KINEMATICS:PROJECTILE MOTION Screen shot Analysis. Answer these questions using complete sentences: 25. What is the independent variable in this experiment (doubts: YouTube video about variables 26. What is the dependent variable in this experiment? 27. What are the control variables in this experiment? 28. What happened to the range or horizontal distance of the projectile as the angle increased from 25-45 degrees? 29. What happened to the range or horizontal distance of the projectile as the angle increased from 45-65 degrees? 30. What angle achieved the maximum range or horizontal distance? 31. Use excel and prepare a graph of: Launch angle versus Range. Insert a X-Y scatter with smooth line graph type: Graph 32. Do you accept or reject your two initial hypotheses and why?
