Today we talked about free fall. For Monday please finish the graphing exploration/activity for the ball.

Today we did a lab where you analyzed a graph (either position or velocity) and then attempted to duplicate the motion by moving in front of a motion detector. The lab is due tomorrow (some groups need to finish the last graph).
Today we worked together to solve some of the tougher kinematics problems from the book. We got through the first 4 problems in the powerpoint. Solutions are available if you want to review how we did these problems.
Today was a work day to complete the pink worksheet. It is due on Monday so if you did not finish it in class, you should finish it over the weekend. The solutions are available in google drive if you would like to check answers, or if you need a hint on a particular problem.
Today we continued working on the speed and acceleration worksheet. Tomorrow will be a work day to complete the worksheet. Any problems that are not done at the end of class tomorrow will become homework because the worksheet will be due on Monday. If you get stuck or want to check your answers, solutions to the worksheet are in the Physics Google Drive folder.
Today we finished deriving the kinematics equations (except 6th period where seniors were gone for an assembly) and began working on the pink Speed and Acceleration worksheet.
Today we used our position vs. time graph for the marble to calculate the instantaneous velocity of the marble. We then talked about what information is conveyed by the different graphs (position graph, velocity graph, acceleration graph). Finally, we began deriving the kinematics equations using our graphs.
Today you gathered data to create a position vs. time graph for a marble rolling down an inclined ramp. Make your graphs as large as possible (fill the entire page!) because we will be using the graphs to derive some equations tomorrow.
Today we put our knowledge of constant velocity to the test in the form of a challenge problem. Students worked with a partner to solve two challenge problems, then they tested their predictions with the buggies. If your prediction was accurate, you won a physics buck. If not, better luck next time!
Tomorrow is a quiz. You should be familiar with position vs. time graphs - know how to determine displacement and distance (know the difference), how to determine average velocity and average speed. Be able to sketch a velocity vs. time graph from a position vs. time graph. Be able to interpret a motion map (you will not have to draw one). Also be able to solve straight-forward problems like we have practiced in class. Today we worked together to solve constant velocity problems involving two objects. We finished all of the problems in class, so there is no homework.
