Unformatted text preview: Angular Velocity • Definition : the rate of change of angular displacement. • Mathematically: Relationship between angular and linear velocity Example • Sample Problem 6.2, p. 155 • The sweet spot on a baseball bat is 120cm from the axis of rotation during the swing of the bat. If this spot on the bat moves 40m/s, how fast is the angular velocity of the bat? Angular acceleration • Definition : the rate of change of angular velocity. • Mathematically: Types of Angular acceleration 1. Tangential acceleration 2. Centripetal acceleration Tangential acceleration • Definition : the component of linear acceleration tangent to the circular path of a point on a rotating object. • Mathematically: Centripetal Acceleration • Definition : the linear acceleration directed towards the axis of rotation. • Mathematically:...
