In Unit 2, we learned mostly about kinematics. Kinematics is the study of motion. We learned how all motion is relative because technically speaking, the whole earth is constantly moving. This picture relates to the unit because it demonstrates motion. The car on the left is moving relative to the other car. The black car appears to be moving toward the red car, but to the black car, it could seem as though the red car was moving toward the black one. If they are both moving, then it would seem as though the other car were moving twice as fast. We also learned about velocity. Velocity is the distance divided by time or speed with direction.
That's a really cute picture, and using the car to help in your explanation made it really clear. Your post as a whole was also really concise, which I like.
ReplyDeleteyour picture was a very creative way of explaining displacement and velocity.
ReplyDeleteOk, I totally commented on this last night but it didn't work, I swear to everything that I did. Uugh, but I like your picture a lot, and you explained relative motion in a clear and understandable way :D
