The Physics of Sitting in Physics Class
I am going to explain a little bit about how physics can relate to me walking to and sitting in my physics class everyday.
First of all, the total displacement from the class I have before this to my physics class is approximately 100 meters. It takes me about 180 seconds to get to my class, because I stop in the hallways and stuff. Using the equation v=d/t, I can them determine that my average velocity is .56 m/s. However, as I get closer to the classroom, my average velocity decreases significantly because I do not want to walk into the class. When I see the classroom, there is about 10 meters left. I try to take at least 30 slow seconds to walk into class, so that would leave me at an average velocity of .33 m/s as I approach the door.
Sometimes when I am sitting in class I wonder what it would be like to throw myself out the window to end the suffering. Then, I wonder if I would survive the fall. To figure this out, I could use one of the kinematics equations. My inital velocity would be zero, because I would be sitting in my chair. I wouldn't know my my final velocity. My acceleration would be 9.81 m/s since I am on Earth, and the total distance from the window to the ground would be about 12m. To find my final velocity, I could use the equation vf^2=vi^2+2ad. Once I plugged in all of my numbers, I determined that my final velocity would be 15.34 m/s. I think I would manage to survive with a few broken bones at least.
So there you go, I hope this just proved even more that physics really can relate to everything!
