Quarter 1 Summary

Quarter 1 Summary

In the first quarter of physics we have learned many things.  The firs thing we have learned was the importance of standards, and more specifically the standards in measurements.  We used an example from old Hawaiian measurements like the pia which is the distance from your extended thumb to your extended pinky.  Another thing we learned was kinematics and motion.  All motion is relative.  So in order to know if something is moving, the question is always, “relative to what?”.  If two cars are going the same speed, they are not moving relative to each other but relative to the road, it is defiantly moving.  Another thing I learned is that the acceleration on Earth is 9.8m/s2.  We also learned the correct way to create a position vs. time graph, a velocity vs. time graph, and acceleration vs. time graph.  We learned how to calculate displacement from a graph and how to sketch the three graphs from information given by the other graphs.  Also we learned about pendulums and periods of time.  We learned how mass and length affected the time it would take the pendulum to swing back and forth five times.  Overall this is the major things we have learned in physics this year.
