__Objectives__ The objectives for today’s class period were illustrated on the board as per usual. The first of which was the daily homework check. The homework that was due today was on learning more about XT graphs. In this worksheet we learned about average velocity, and average speed. The worksheet included illustrations of a walk took by Mr. Physics, and it explained how to find the values for speed and velocity. It gave formulas such as average velocity = delta x over delta t, and average speed = distance over time. The formula for average velocity is used to find the displacement of an object over the amount of time. The worksheet then asked us a number of questions to make sure we knew exactly how to use the formulas. The next objective was the Daily Question. Today’s DQ was all about the lab we had just completed entitled Graphin’ the Walk. It asked whose walk was slowest, fastest, the most constant, the least constant, etc. We looked at a graph on the smart board to figure out the answers as a class. The third objective was reviewing the homework, and the final objective was a class activity. __Homework Assignment__ The homework for tonight was once again concerning average speed and velocity. Word problems were given with distances and times to find the answers. After finding the average speed and velocity you then had to convert the answers from miles per second to miles per hour. After the conversions were complete the worksheet asked a few more questions on the word problems. A more in depth knowledge of both average speed and velocity were to be gained by completing this activity. This diagram shows how to find the average velocity and average speed of an object through a number line.
