Objectives Define Centripetal Acceleration.
Calculate Centripetal Acceleration. Describe why Centripetal Acceleration is center seeking.
5
Centripetal (center seeking) acceleration - a change in direction of velocity
ac = centripetal acceleration (m/s2) vt2 r2 r vt = tangential speed (m/s) = angular speed (rad/s) r = radius (m) ac = ac=

A test car moves at a constant speed around a circular track
A test car moves at a constant speed around a circular track. If the car is 48.2 m from the track’s center, and has a centripetal acceleration of 8.05 m/s2, what is the tangential speed?
