Unit 2

Unit 2 was all about Kinematics which is the study of motion. Today we did the "Physics Olympics" lab which compared the velocities of different activities such as running, walking and jogging. Using our data, we made a graph where the independent variable (time) showed a direct relationship with the dependent variable (distance traveled) for all 4 activities. Then, we learned how to find the average velocity which was the total distance traveled (per activity) divided by the total time elapsed of the same activity which gave us the slope of the line (average velocity) in meters per second. Doing this lab demonstrated the applications of the formula for velocity and vectors. Once we better grasped the ideas of going in straight lines which on a graph would create a positive slope and therefore a positive velocity, we then added in things like change in velocity, immediate velocity, and negative velocity which was essentially going in the opposite direction. This graph shows our data from the lab we did in class.
