On Friday we got to learn even more about kinematics and a lot about graphing. Mainly position vs. time graphs and velocity vs. time graphs through experiments with motion detectors, Logger Pro, and wooden boards. Some of the main key points we were looking at were time, displacement, velocity, and distance. We were trying to replicate graphs on Logger Pro by holding the flat wooden board up to the motion sensor. Overall it seemed like the position vs. time graphs were easier to replicate since, at least for me, it was easier to see the distance and speed needed for that graph. While the velocity vs. time graphs seemed more challenging since it required more sudden changes in direction and speed.
This is a picture I took at a train station near Fushimi Shrine in Kyoto, Japan. I thought it was a good example of an object with velocity because trains start, stop, speed up, and slow down all the time. Also when in motion, the train is always moving in a direction.
You summed up the lab pretty well, I agree that replicating the position vs. time graphs were easier than the velocity vs. time graph.
ReplyDeleteI agree position vs. time graph's were easier for me to replicate because like you it was easier to replicate speed and distance than acceleration. PS I really like your background
ReplyDeleteYah I thought it was interesting how we had so much trouble with the other one! and thanks haha
