Angular Kinetics Exam Review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Joint Torques - CORRECT ANSWER - Forces that cause joint motions
Newtons 2nd Law - CORRECT ANSWER - F = ma
Newton's 2nd Law in Rotation - CORRECT ANSWER - T = I𝛼, where I = moment of
inertia and 𝛼 = angular acceleration
Static/Slow Movement Situation - CORRECT ANSWER - 𝛼 ≈ 0, ∑ 𝑇𝑒𝑙𝑏𝑜𝑤 = 0
Dynamic Movement Situation - CORRECT ANSWER - 𝛼 ≄ 0, ∑ 𝑇𝑒𝑙𝑏𝑜𝑤 = 𝐼𝛼
High accelerations - CORRECT ANSWER - Require greater forces, demanding greater
muscular torques
Centripetal Acceleration - CORRECT ANSWER - Acceleration of an object on a circular
path, always directed toward the center
Centripetal Force - CORRECT ANSWER - Force needed to maintain circular motion,
given by Fc = mrω2
Centrifugal Force - CORRECT ANSWER - Apparent, inertial force acting on an object
moving in a circular arc, tending to throw the object away from the center
Hammer Throw - CORRECT ANSWER - Fc = 1108 N (249 lbf)
