  1. Review of rotational motion Reference line

  2. si θi

  3. sf θ θf θi

  4. s θ θf θi r

  5. s θ r θf θi r

  6. at at vt For increasing vt For decreasing vt

  7. Review of angular quantities • Displacements • Speeds • Accelerations • = i + t  = it + (1/2)t2 2 = i2 + 2

  8. Rotational kinematic equations vt = vti + att r r r =>  = i + t Similarly: 2 = i2 + 2 θ θ = it + (1/2) t2
