  1. Circular Motion Round and Round

  2. Circular Motion Velocity is always changing because when traveling in a circle the direction is always changing!

  3. Circular Motion It is often best to describe circular motion in the time it takes to complete one circle or T

  4. Circular Motion It we know the radius of the circle r we can calculate centripetal velocity using the circumference = 2πr

  5. Circular Motion 2πr v = T

  6. Circular Motion When objects are moving in a circle the acceleration is towards the center!

  7. Circular Motion 2 v a c = r

  8. Circular Motion Now we substitute our velocity equation for v 2 v a c = r

  9. Circular Motion Now if we know time we can find centripetalaccelerationa 2 4πr a c c = 2 T

  10. Circular Motion Solve this equation for velocity 2 v a c = r

  11. Circular Motion Now we can find our centripetal velocity v = a r c

  12. The End
