Chapter 10 Summary

• This chapter introduced simple rotational or angular kinematics.
• All human movement involves angular motion or the movement of a body segment about its axis of rotation.
• The kinematics of rotation are similar to their linear counterparts in that they can be represented as vector and scalar quantities.
• Angular displacement is the change in angular position of a line segment; angular velocity is the rate of change in angular position; and angular acceleration is the rate of change in angular velocity. They are all vector quantities.
• The relationship between linear and angular velocity was discussed and calculations of displacements and velocities were introduced and practical applications provided to enhance understanding.
