Today we talked about the concept of instantaneous velocity, and used tangent lines to find the instantaneous velocity of the marble at various times as it rolled down the ramp. We then graphed velocity vs. time and discovered that the velocity was increasing at a constant rate (linear relationship).

You finished collecting your data for the marble lab, then you graphed it. We discussed the shape of the graph, what it meant, and started to analyze it. We introduced the concept of instantaneous velocity and you worked on calculating the instantaneous velocity for your marble at 5 different times.
Today we gathered position and time data for a marble rolling down an inclined track. Tomorrow we will graph the data (or finish collecting data if you are still working on it) and discuss our findings.
Today we reviewed the constant velocity packet. Solutions are available in google drive. Topics to understand for the quiz: distance, displacement, speed, velocity, how to interpret a position vs. time graph (speed, direction, starting position, displacement, distance), how to interpret a velocity vs. time graph (speed, direction, displacement), how to solve constant velocity problems with one object or two objects (crashing buggies, or chasing buggies) using the constant velocity equation we derived.
Today we did a lab challenge - you had to predict where two buggies would meet in 2 different scenarios. We then tested how good your predictions were. If you did not finish the packet in class, please finish from problem #9 to the end.
Today we began a packet with practice problems that include the concepts of interpreting and drawing various types of graphs, distance, displacement, speed, velocity. We will continue working through the packet tomorrow. Quiz on Friday covering these concepts.
Today we applied understanding of distance, displacement, speed, velocity, and uniform motion to solving problems (slides 38-44 in yesterday's PPT). Enjoy your weekend!
Today we practiced taking a verbal description and creating a position vs. time graph, and vice versa (see slides 15 - 37). We also practiced going from a position vs. time graph to a velocity vs. time graph. Then we reviewed some definitions and tried some practice problems.
Today we used the motion detectors to "walk" various position vs. time and velocity vs. time graphs. On Thursday, this lab, and the buggy lab (graph and packet) are both due.
