What I Learned This Semester...

                      

This semester I definitely learned a lot about physics. From simple concepts like acceleration, velocity, scalars/vectors, and other terms, I have expanded my knowledge and outlook on different aspects in life. From simple kinematics, to 3-D kinematics, to momentum, and finally to energy, I think a person would’ve had to be totally oblivious to not take something away from this semester. I think my favorite section that we learned, even though it was our last, was energy. I found it interesting how everything has energy in some sort of way. We can find how much energy is stored in one specific object, such as a spring. When it’s compressed, it actually has stored energy, very interesting. In my picture, I chose a picture of the wind chimes that are outside my house, and a toy car that was in my garage. I chose these thinsg because now I can actually apply to physics to real life situations. If I wanted to calculate the maximum speed at which the wind chime goes when the wind is blowing it I could. If I wanted to find out the acceleration of the race car, and its velocity, I could. I realized that with the concepts I learned, I can apply it to a lot of things in life.

                This semester I found that learning physics can be fun. Thank you Mr. Blake for making the first semester  fun and easy to learn. Even though some concepts were hard to grasp, you made it easier  for us to learn them, and actually utilize them. I learned this semester that you and Mr. Freitas make an excellent singing group, haha. Overall this semester was really fun, and I hope to learn more in the upcoming semester.



Energy

This week in physics, we learned about energy and "work." We learned about gravitational potential, and spring potential. An important law that we learned was the law of conservation, which states in an isolated system energy is neither created nor destroyed. Above is a picture of a sling shot, which is similar to a spring. When pulled back it is compressed, to find the potential of it you need the distance at how much it is pulled back, and the k which is the spring or in the case, the sling shot constant. I also learned about gravitational potential which is found when given the mass, the force of gravity, and the height at which an object is at in relation to the ground. I learned alot of new concepts and formulas this week in relation to energy and "work."
