Chapter 6: Motion in a Circle


Kinematics of uniform circular motion
Centripetal acceleration
Centripetal force



(a) Express angular displacement in radians.

(b) Show an understanding of and use the concept of angular velocity to solve problems.

(c) Recall and use v = rω to solve problems.

(d) Describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle.

(e) Recall and use centripetal acceleration a = rω², and a = v²/r to solve problems.

(f) Recall and use centripetal force F = mrω², and F = mv²/r to solve problems.
