  1. Notes 6.2: Circular Motion

  2. Circular Motion – when a force causes an object to curve in a full circle. • There are 2 types of circular motion to be familiar with: • 1.Rotation – an object spins around an internal axis. • Example: bike tire, figure skater • Earth rotates once on it’s axis in 24 hours

  3. 2. Revolution – object moves around an external axis • Example: rider on a carousel • Earth revolves around the sun

  4. We can describe circular speeds in 2 ways. • 1. Angular speed – rate at which something turns (rpm) • A CD spins at 200 rpm

  5. 2. Linear speed- distance traveled around the circle divided by time. • Units: m/s

  6. Example: A CD takes 0.3 seconds to make one revolution. If the radius of the CD is 6 cm, how fast is a speck of dust on the outside of the CD moving? • Answer: • t = 0.3 sec. v =(2πr)/t • r = 6cm = 0.06m v = (2 x 3.14 x .06)/0.3 • v = ? v = 1.26 m/s

  7. When an object is rolling, it has both linear and rotational motion.
