If a section is highlighted, it needs your attention. Do not turn in your lab with anything highlighted! Names 1. Title-Projectile Motion Lab 2. Purpose-The purpose of this experiment is to observe projectile motion, plot the path of a projectile with velocity vectors, and to determine the angles of ideal launch for vertical displacement and horizontal displacement. Questions: a. At what angle does a launched projectile attain the greatest vertical distance? b. At what angle does a launched projectile attain the greatest horizontal displacement? c. What is the relationship between angle of launch, horizontal displacement, and vertical displacement? 3. Hypothesis (predictions) a. I predict that… b. I predict that… 4. Procedure 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 5. Data Table-Complete the data table. To draw a curved projectile path click on “autoshapes”, “lines”, and “curved lines”. After the “insert drawing here” comes up, click “control z” and draw in the appropriate box. To draw vectors, click on the arrow in the lower left pane. It will take a few times to get the hang of this. See example below. Means of Launch Angle Trial Horizontal Displacement (m) (Degrees) 1. Kicking 15 a. b. c.

Projectile Path with Velocity Vectors Estimated Vertical Distance (m) Observations-Make your own observations about the motion of the projectile. The more the better. Be sure to include observations about instantaneous horizontal/vertical velocity and average horizontal/vertical velocity. 6. Results (graph here) Click on insert, picture, and chart.
