Exploring Forces and Motion in Circular Dynamics: Key Questions and Concepts

This presentation delves into various questions related to circular motion, specifically focusing on the dynamics of objects in vertical and conical pendulum movements. It addresses key queries about forces acting on masses, such as tension (T) and gravitational force (Mg), and their variations when accelerating upwards or downwards. Additional inquiries examine the directions of tangential velocity and centripetal acceleration at different points in a counterclockwise (CCW) circle. This material serves as an excellent review for understanding the fundamentals of circular motion.

Presentation Transcript

  1. Circular motion part 2 • The questions in these slides were not asked with clickers during the summer 2007 session, despite some votes being tallied. These questions were asked orally in class, however.

  2. Which force is bigger for a mass being accelerated upwards by a string? • T • Mg • same

  3. Which force is bigger for a mass being accelerated downwards by a string? • T • Mg • same

  4. Which direction is the tangential velocity at the top of a CCW circle • Up • Down • Left • Right

  5. Which direction is the centripetal acceleration at the top of a CCW circle • Up • Down • Left • Right

  6. Which direction is the tangential velocity at the bottom of a CCW circle • Up • Down • Left • Right

  7. Which direction is the centripetal acceleration at the bottom of a CCW circle • Up • Down • Left • Right

  8. Which force is bigger at bottom of a vertical circle? [see also next slide, which appeared earlier] • T • Mg • same

  9. Which force is bigger for a mass being accelerated upwards by a string? • T • Mg • same

  10. Which force is bigger at top of a vertical circle? • T • Mg • Same • Insufficient information is given. (Good practice for you: why is this true?)

  11. What is the radius of the circle in conical pendulum, string length = L, revolving in a circle angled theta relative to the vertical. • L • Lsin theta • Lcos theta
