Kinematics is the study of motion (which includes distance, scalars, vectors, displacement, speed, velocity, instantaneous speed and average speed. Today I decided to do my homework on the living room floor. I took all my books and papers to the living room and laid them out and began to work. As I came to my economics homework, I realized that the assignment was to make a poster, but I didn't have any construction paper or markers with me! So, I stood up and walked down the hall and up the stairs to my bedroom to grab some construction paper and markers, and then I walked all the way back to where I was working. The total distance traveled was about 120 feet. Distance is the total path length (how far). But, even though the distance traveled was 120 feet, my displacement was 0. Displacement is how far you went in relation to your starting point. Going all the way to my room and back made my displacement 0 because I did not move anywhere in relation to my starting point. Kinematics is displayed in our everyday lives, whether its running, or walking, or maybe even driving. Kinematics is important to learn because it can tell you many things about motion.
Haha that's the worst ! Right when you get settled you realize you forgot something and have to take the time to stand back up and get whatever it is you forgot. I do that all the time !
ReplyDeleteNice one Mel! haha. but good connection to something so simple. Sometimes we don't realize it but this physics stuff is in our everyday lives. I liked how you connected both distance and displacement into this situation and it made total sense, probably because this happened to me before too :(
