Motion that relates to Biomechanics

1. Describe the motion with a. Kinetics b. What is Angular kinematics? i. Distinguish Distinguish angular motion from rectilinear and curvilinear motion. ii. Review Chapter 1 c. What is the unit of measurement for angular motion? d. What are the tools used to measure body angle? 2. Distinguish relative and absolute angles. a. Calculating absolute and relative joint angles using trigonometric formulas and winter convention - see examples from the slide. 3. Why do we use an instant center of rotation? 4. Describe our joint angle (of hip, knee, and ankle) interpretation at different phases of walking (locomotion). 5. What is the significance of the right-hand thrumb rule in angular motion? 6. Discuss the following concept with formulae and units. a. Angular distance and displacement. b. Angular speed and velocity. c. Angular acceleration. 7. Explain the relationships between linear and angular motion. a. Angular and linear displacement, angular and linear velocity, and angular and linear acceleration. b. Solve mathematical problems based on the formulas discussed in this chapter. See examples from the slide. 8. Know how to use the equation of constant angular acceleration to solve the problems. 9. Discuss the application of angular kinematics. 10. Describe our joint angle (of hip, knee, and ankle) changes when walking vs running.
