Unformatted text preview: 1 Announcements 1. HW6 due March 4. 2. Midterm1: if you want to look at your scantron, see Prof. Chan before end of today 3. Solutions to even number questions in textbook starting Chapter 6, numerical values will be posted in the HW solutions page (after HW6 is due). The Radian The radian is a unit of angular measure The radian can be defined as the arc length s along a circle divided by the radius r s r = Average Angular Speed The average angular speed, , of a rotating rigid object is the ratio of the angular displacement to the time interval f i av f i t t t = = Unit: rad/s Average Angular Acceleration The average angular acceleration of an object is defined as the ratio of the change in the angular speed to the time it takes for the object to undergo the change: f i av f i t t t = = Unit: rad/s 2 Relationship Between Angular and Linear Quantities Displacements Speeds Accelerations Every point on the...
