New experiment. New toys. New knowledge to gain. The activities we are doing in the lab seem to be getting more and more interesting as time flies by. For today, we analyzed the mechanism of a projectile motion. We use new sets of instruments such as the projectile gun and a metal bullet. Other instruments were meter stick, tracking paper, and marker. The experiment was divided into two parts. The first one is analyzing the trajectory of a body in a projectile motion and the second one is analyzing the relationship of the angle of projection of the metal ball to the horizontal distance it covers after it was launched. Since projectile motion has a theoretical background, it is also our mission to analyze the adherence of the results of our experiment to the theoretical one.
We managed to do “division of labor” to effectively work on the experiment. Each of us did a turn in setting up the projectile gun because it would be grueling for anyone to do it all alone all throughout the experiment. For the first part of the experiment, we recorded the height of the trajectory by tracking the marks that metal left as it hits the paper posted in the wooden block. We recorded several trials for the different distances of the wooden block from the projectile gun.
For the second part of the experiment, we recorded the horizontal distances that were travelled by the metal ball in different degree of projection of the gun. We also did several trials for each of the degree of inclination.
