Activity 85: Rotational Kinematics

Rotational (Angular) Kinematics is similar to Linear (Translational) Kinematics


Our previous knowledge of translational kinematics and motion can be extended to describe rotational kinematic motion.


A radian 𝚹 in rotational kinematics is analogous  to displacement in linear (translational) kinematics


When linear distance, (d,s,x,etc…), was measured, we used meters or similar metric unit.  Now we must use radians to measure angular or rotational distance, θ.


A radian “𝚹” is analogous  to a meter


Thus an angle will be analogous to distance .

Relationship

s = r𝚹
 𝚹 = s/r

Activity 85.10

Read Section 10.1 in the textbook.
Pick up a copy of this Seminar Problem 1 and complete.


Activity 85.20

Pick up a copy of this Angular Motion & Acceleration Worksheet and complete. When done check your answers here.


The equations and concepts you learned in Translational Kinematics have an analogous relationship to Rotational Kinematics. 







Activity 85.30  




Activity 85.40

- Do problems 5-9 on page 356 in the textbook.   When you are done check your answers here.
