Overall, I have really enjoyed and benefited from physics this year. We learned about motion, Newton's laws and forces, energy, and systems. I feel as though everything I learned about each of these units will help me at some point in my life. I was most interested in bottle rockets, because it was interesting to see how the concepts we learned in or other units connected with the bottle rocket. The four units we studied this semester all connected to each other, which was exciting. I was surprised when i learned the law of conservation of energy, that says "energy cannot be created or destroyed, although it can be changed from one form to another" and how this connected to our marble roller coaster lab. I found that the projectile motion problems were a little tricky, but eventually got a hang of it.
