  1. Rotational and Circular motion

  2. Lady bug activity directions: In this activity, you must include values that you measureandshow sample calculations to support your answers to the questions. Include examples that use both bugs in different locations.

  3. Sample calculations include: Equation: PE=mgh Substitution: PE = .50*9.81* 2 Answer with units: 9.81 J

  4. B A C D 1. A bug is spinning on a platform with constant speed, what was the direction of acceleration at the blue point? Beginning of test End of test E none of these Velocity is the green vector

  5. Answer to previous slide Beginning of test End of test A: acceleration vector always points radially for constant speed

  6. CT cir 1

  7. Ct 1 cir answer

  8. 2. A bug is on a platform spinning clockwise & speeding up. Which best shows the bug’s acceleration direction at this spot? C B A E D

  9. Answer to previous slide B: If the acceleration is constant and increasing, the vector will be not radial, but off to the same side of the radius as the velocity vector.
