Physics 312 Lecture: "Rotational Kinematics" Mar 9, 1998

• Physicists usually use radians rather than degrees to measure angles.
• There are 2*pi radians around a circle.
• Radians may sometimes disappear as units in a problem, especially in angular velocity or angular acceleration.
• Angular distance (radians) is analog to linear distance (meters).
• Angular velocity (radians/sec) is analog to linear velocity (meters/sec).
• Angular accleration (radians/sec^2) is analog to linear accleration (meters/sec^2).
• Equations of rotational kinematics are very similar to those of linear kinematics.

This lecture discusses material in Chapter 10 of Serway.
