Unformatted text preview: Angular Acceleration The rotational corollary of linear acceleration is angular acceleration, the rate of change of angular velocity. In the same manner as we derived the equations for average and instantaneous velocity, we define angular acceleration: = = These equations for angular displacement, velocity, and acceleration bear striking resemblance to our definitions of translational variables. To see this, simply substitute x every time you see , v every time you see , and a every time you see . The yield are the translational equations for displacement, velocity, and acceleration. This similarity will allow us to easily derive kinematic equations for rotational motion...
