What does human movement look like in a graph? Consider the graph below, excerpted from the book series Walk, Jog, & Run: The Science of Athletic Training from Schottenbauer Publishing.
- In which direction is the walker moving?
- How many steps are shown in the graph?
- How can the speed of the walker be measured on the graph?
- Describe the movement of the knee, ankle, and toes relative to the hip, as if the hip were stationary.
- Which body part moves the most in the x direction?
- Which body part moves the most in the y direction?
- What is the velocity of the walker?
