This is one in a set of 3 videos which can be used to investigate a force’s effectiveness at causing rotation. During a discussion of the class results, the concept of “torque” can be introduced.

Data Collection:
Measure the size of the force applied to each side of the bar at different times in the video. Make note of the distance each force is applied from the pivot point.
Data Analysis:
Graph the size of the force applied to the right side of the bar on the y-axis and the size of the force applied to the left side of the bar on the x-axis. Consider the significance or meaning of the slope of the graph and the y-intercept of the graph.
