Today we began setting the stage for our study of motion by defining position, displacement, distance, speed, and velocity. We also learned how to read and use motion diagrams to model different types of motion. Homework was a worksheet which is due tomorrow (most students completed it in class and already handed it in!)
Today we talked about the data we collected during the lab, how to interpret the graphs, and how to write the equation of the best fit line. Then we completed the ball bounce challenge. Some teams were successful, others just barely missed the mark! Don't be stressed out if you did not earn a physics buck in today's challenge, there will be many more opportunities to come! The completed lab packet is due on Wednesday 9/9. Make sure you staple your graph to the lab packet. Enjoy the long weekend!
Today you designed a controlled experiment to determine the relationship between the drop height of a tennis and its rebound height. You should have collected your data in a neat and organized data table. Make sure you graph your data points. Remember that the independent variable goes on the x-axis, and the dependent variable goes on the y-axis. Draw the best fit line using a ruler, then write the equation of the line (hint: you will need the slope of the line, and the y-intercept). We will talk about the data, test your predictions, and complete the rest of the packet tomorrow in class. No homework tonight (unless you are not done graphing, in which case you should finish your graph and find your equation before class tomorrow).
Today in class you received a copy of the syllabus. Make sure you read and understand the class policies. The signed acknowledgement (electronic) is due next Wednesday.
We worked in teams to complete the marshmallow challenge. Many interesting architectures were created! Congratulations to the winners who each received a physics buck which can be exchanged for extra credit. |
