Unformatted text preview: Physics 101: Lecture 16, Pg 1 Physics 101: Physics 101: Lecture 16 Lecture 16 Rotational Kinematics Rotational Kinematics Todays lecture will cover Textbook Chapter 8 Physics 101: Lecture 16, Pg 2 Rotational Kinematics Rotational Kinematics The motion of a rigid body about a fixed axis is described by using the same concepts as for linear motion (see C&J Chapter 2): Displacement ( ), Velocity ( ), Acceleration ( ) Angular Displacement: Identify the axis of rotation and choose a line perpendicular to this axis. Observe the motion of a point on this line. How can one define the change of position of this point during rotation about an axis ? Answer: Change of angle the line makes with a reference line: Physics 101: Lecture 16, Pg 3 Angular Displacement Angular Displacement Follow point P on line perpendicular to the rotation axis: t=t : t=t f : =0 f- f Angular displacement: = f- = f = - f SI unit: radian (rad) 1 rad = 360 degrees/(2...
