Week 17 Reflection

This week in physics, our class focused on projectiles and their motion. To do this, we experimented with different objects launched in two different directions. We looked at the landing times of an object dropped and the other thrown to the side. It was concluded that both objects would land at the same time due to their gravitational pulls acting on their inertia. Their pull from the earth differs, however, it is needed to overcome their inertia, causing them to hit at the same time. We did this in the classroom with two balls and on the roof launching the rockets. We found it to result in the same position with both circumstances.

We also looked at the speed of the projectiles and how they have horizontal and vertical tendencies acting upon them. The object continues going straight due to its inertia, or tendency to continue what it's doing, but it starts to gradually slope downward due to the earth. However, when the projectile is in motion, it moves at a constant velocity. I also learned that the time it takes divided by the horizontal range equals the initial launching speed. Thus, the change in velocity over the change it time calculates the acceleration of the object on the ramp.

On Friday, we were to have our final assessment of the semester, but instead of having a normal assessment on paper, each group was assigned a number to complete on whiteboards. This way the class could discuss the answers an show they came to them. This personally took a lot of pressure off of me and prepared me for the midterm. For the midterm on Friday, I plan to complete the review study guide on google drive and put as min as I can on my note shirt. Due to studying for my other classes, I have not started my shirt yet, but it will get done.

Wish me luck on my exams! :)
