In this experiment, I used a projectile launcher to fire a ball horizontally and different angles. I used this information and my knowledge of physics to predict where the ball will land when it hits the floor.

Materials Experimental Procedure
The purpose of this experiment is to distinguish the distance from different angles and also calculate the height of each angle. As a result, we can conclude that 45 is the angle that goes farthest compared to other angles. If the angle is increased, 45 degrees will always be the angle that will go farthest. However, the height is increased as the angle is increased so the highest one in the experiment is going to be 60 degrees and the lowest one is 30 degrees. We have to position the launcher in the correct place to launch the cannon into the carbon paper. However, when we do the experiment for 40 angles another classmate group has a problem with their pump pressure so the instructor swaps the pumper with our group. Then, our data has a mistake but we have to continue to do the experiment. For instance, for 40 degrees, before swapping the pumper, the data is about 195 cm but when we change the pumper, it becomes about 190 on both 2 times. What I learned about in this chapter is vectors,(magnitudes and directions), vector kinematics in two dimensions, vector dynamics as well as motions, forces, velocity and scalar (magnitude only). What I found that I have difficulties about this chapter is projectile motion in two dimensions, because the applied equations often confused me with the graphs, and the questions. My strength and weakness is often reading and actually understanding the questions. |
