Today we discussed the worksheet that was completed for homework yesterday (using graphs and motion maps to describe motion, and interpreting position vs. time graphs). Then we worked in groups on some of the constant velocity problems from the book. No homework tonight.

Today we learned how to describe motion using motion maps (or motion diagrams). We then practiced describing motion using graphs, words, and motion maps. Please finish the worksheet tonight if you did not finish it in class. We will go over it tomorrow in class.
Today we reviewed the concepts of position, displacement, and velocity. Then we began to analyze our position vs. time graphs for the motorized cars. We discussed the meaning of the slope of the position vs. time graph (it's the velocity) and the y-intercept (it's the car's starting position). We attempted to make a velocity vs. time graph, but things got very confusing very quickly because everybody had different data. We will attempt this again tomorrow using a common data set.
Today we played with the motorized cars. You collected data to create a position vs. time graph for two different buggies - a fast buggy and a slow buggy. You may graph both buggies on the same axes, but please make sure that you label which line belongs to which car. You should draw a line of best fit for each buggy, and calculate the slope (don't forget units!) for each line.
Today we concentrated on learning the definitions of several physics words: distance, displacement, speed, velocity. Homework is a worksheet that is due tomorrow.
Today we talked about the graphs that we created from the ball bounce lab. We discussed the physical meaning of the slope and y-intercept, and used the information to write the equation of the best fit line. Then you calculated the drop height needed to give you the target rebound height, and tested your prediction, earning a physics buck if your prediction was accurate. If you completed and handed in all of your graphs and calculations today during class, you have no homework. If you did not hand in your graphs and calculations, please complete them this weekend and hand everything in on Tuesday. This is your first lab grade. Enjoy the long weekend.
Today we designed an experiment and gathered data to answer the question "how does the drop height of a ball affect its rebound height". Everyone was able to gather their data and create their graphs. Tomorrow we will finish up with slope calculations and discuss the meaning of the slope and y-intercept, then do the ball bounce challenge. Today's powerpoints (including instructions for what needs to be handed in) are available on google drive in the week 1 folder.
