Lab 2: Projectile Motion

Endri Pashollari PHY2053L.521F 10/10/ Wayne Mathe

I. Introduction This lab focuses on understanding the relationship between initial velocity, angle of projection, and the projectile's time in flight and range. Projectile motion is the path an object follows when thrown or projected, subject to only gravity's force. By analyzing a steel sphere's motion when launched horizontally, we can derive the kinematic equations. Furthermore, by understanding the horizontal and vertical motions, the principles of Newtonian mechanics predict the path of the ball. A. “Does the time-of-flight of a ball launched horizontally off a table vary as the initial velocity is varied?” B. “Can we predict and verify the range and the time-of-flight of a projectile launched at an angle?” II. Methods/ Procedures A. Materiels:

1. Vernier Projectile Launcher
2. Vernier Time-of-Flight (TOF) Pad
3. Steel balls
4. LabQuest Mini
5. Computer with Logger Pro
6. Hand pump
7. Meter stick
8. Safety goggles
9. Plumb bob
10. Carbon paper
11. Binder clip B. Diagram of Lab Setup:

IV. Discussion/ Analysis A. From the data and the graph, it's evident that the time of flight remains unaffected by the initial velocity when the ball is launched horizontally.
