Analysis 1. Make a graph of height vs range using all 8 data points. Remember to include titles 2. Determine the "muzzle" velocity, or v, of the launcher using your most consistent range result. Show all calculations 3. Assuming your muzzle velocity is constant through all four heights. Use your value to find the theoretical range based on the height of each launch site. 4. Determine the experimental percent error between the actual vs theoretical range for each height % error #experimental - #actual | x100 # actual Conclusion 5. How does the initial height effect the range of a projectile? What trend to you see in your graph? How well did your data match the theory? 5. Describe at least two sources of error present in this investigation, and state two ways in which the error present could be reduced. Introduction When considering horizontally launched projectile motion, two variables can be of utmost importance: Purpose Height the projectile is launched from, or the vertical displacement, which determines length of time in the air. Horizontal distance, or range, a projectile travels. The purpose of this investigation is to measure the vertical displacement, or height of the launch, and the horizontal displacement, or range, travelled by a projectile Procedure Design and build a piece of equipment that would allow you to horizontally launch a projectile with a fixed velocity from various heights. It is imperative that the launch speed be uniform so various methods are possible: A ramp of fixed height which allows a ball or "hot wheels" car to roll down to a horizontal take-off ramp. A spring launched toy. Your choice.
