• ### Rotational and circular motion clicker questions

1. 1. Rotational and Circular motion
2. 2. 1. A bug is spinning on a platform with constant speed, what was the direction of acceleration at the blue point? E none of these Velocity is the green vector D A C B Beginning of test End of test
3. 3. Answer to previous slide A: acceleration vector always points radially for constant speed Beginning of test End of test
4. 4. CT cir 1
5. 5. Ct 1 cir answer
6. 6. 2. A bug is on a platform spinning clockwise & speeding up. Which best shows the bug’s acceleration direction at this spot? A B C D E
7. 7. 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.
