Kinetic energy represents the kinetic energy of the whole body. Near the maximum value, the movement is dynamic, indicating that the body is actively performing an action. Near the minimum value, the movement is static, suggesting that the body is preparing to act. 

To calculate the frame length, count the total number of frames in the dataset. Each frame represents a data point collected over time. The total frame length gives the duration of the motion or activity being analyzed. In this dataset, the total frame length is determined by the number of entries in the data array.
