This lab uses Tracker 4.0 video analysis software to measure and analyze the center of mass motion of a person landing after a jump. Students measure the acceleration of the person in free-fall and his acceleration while he is landing and slowing down. Students use the data to calculate the force of impact by the floor on the student during the landing. There are two video files: (1) the student bends his knees a maximum amount during the landing in order to decrease the force of impact by the floor; and (2) the student bends his knees a small amount in order to increase the force of impact on the floor.
The zip file contains two folders: (1) a long time interval during the landing and (2) a short time interval during the landing. Each folder includes the lab handout, a video, and a Tracker 4.0 file. The video was recorded by Aaron Titus at High Point University.
