Physics Chapter 5: 1-4 Circular Motion Basics


Reading Preparation

Text Reading: Giancoli, Physics - Principles with Applications, 5: 1-3

Study Points

Key Equations

Small angle approximation for change in velocity during circular motion:

Δ v v   =   Δ l r

Small angle approximation for acceleration during circular motion:

a   =    Δ v Δ t   =   v   Δ l r   Δ t

Radial acceleration:

a R =   v 2 r


T   =   1 f  

Circular velocity in terms of period

v   =   2 π r T

Force required to keep a body moving with circular motion: F R   =   m a R   =   m   v 2 r

Banking speed

F N   sin   θ =   m   v 2 r

Study Activity

The Gravitron was one of my favorite carnival rides. You can simulate the forces of the ride in Gravitron. See if you can determine the minimum coefficient of static friction required to keep an object in place.

Lab Work

If you want lab credit for this course, you must complete at least 12 labs (honors course) or 18 labs (AP students). One or more lab exercises are posted for each chapter as part of the homework assignment. We will be reviewing lab work at regular intervals, so do not get behind!
