Circular+Motion+Review


 * __Formulas:__**
 * Linear Speed-- distance/time
 * Fnet= m( v squared)/radius
 * Circumference= 2(3.14)r or 3.14d
 * Ca= v squared/radius or Ac= v squared/radius
 * revolutions= distance/circumference
 * __Vocabulary:__**
 * 1) **Circular Motion-** Movement of an object at constant speed around a circle with a fixed radius.
 * 2) **Axis-** Straight line around circle which rotation takes place.
 * 3) **Rotation-** Object turns around an internal axis.
 * 4) **Revolution-** Object turns around external axis.
 * 5) **Centripetal Speed-** Causes an object to follow a circular path.
 * 6) **Centripetal Acceleration-** Always points towards the center if the circular motion.
 * 7) **Period (T)-** Time needed for an object to make one complete revolution.
