Sai Module 4 Lab: Projectile Motion
Lab 4 Projectile Motion
Sai Moua
Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly, we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as, “the motion of objects that are initially launched –or “projected”- and that then continue moving under the influence of gravity alone” (82). Gravity is the lone force acting on the projectile when in motion. There are two components to a velocity vector. The horizontal velocity component is the effect it has on moving the projectile horizontally. On the other hand the vertical component affects the velocity by moving the projectile vertically. …show more content…
We used carbon paper on top of white paper to determine where the ball lands on the floor. We then shot the ball at angles of 30, 35, 40, 45, and 50 degrees. We recorded the distances after each shot and determined that shooting the ball at 40 degrees gave us the maximum range. We kept the launcher at a medium setting and shot the ball straight out 5 times and determined what the average range was at this degree. We used that data to determine that the initial velocity was 4.627 m/s. Next we chose our own angle which was 22 degrees and predicted that the range would be 2.57 meters. We then shot the ball 5 times and determined the average range of flight was 3.03
