PM [08] Phonon Processes in Circular Motion

  1. 1. © ABCC Australia 2015 PHONON IN CIRCULAR MOTION
  2. 2. © ABCC Australia 2015 Phonons in Circular Motion According to the Eskade theory, all motions of material particles are caused by phonons. Circular motions are of no exception although their processes are more complicated than those of linear motions. So let us examine in detail to see what kind of role the phonons play in circular motion. The staging of the analysis is in step with the previous discussion in which we talked about the cyclical nature of the centripetal and centrifugal forces.
  3. 3. © ABCC Australia 2015 𝑣 1. A free particle The phonons are carrying the particle towards the top of the paper at a constant speed 𝑣 in a vacuum. P
  4. 4. © ABCC Australia 2015 𝑣 2. Caught by a string The particle is suddenly being caught by a string fixed at A. A P No tension Fixed Contact established at this point
  5. 5. © ABCC Australia 2015 𝑣 3. The formation of the centrifugal force This effort trying to make the string longer constitutes a new force – this is the origin of the centrifugal force 𝐹⊤. 𝐹⊤ A P Part of the phonons turns around and sets up a centrifugal force 𝐹⊤
  6. 6. © ABCC Australia 2015 𝑣 4. Tension formed in string The string now is under tension and the stress is transmitted to the point at A. Because the anchor point is fixed, it absorbed the incoming force 𝐹⊤. A 𝐹⊤ 𝐹⊤ being transmitted to A Tension 𝐹⊤
  7. 7. © ABCC Australia 2015 5 Production of centripetal force 𝐹⊥ In turn point A produces a reaction to counteract the incoming force 𝐹⊤. This produces a centripetal force 𝐹⊥ equal in magnitude to 𝐹⊤. 𝑣 A 𝐹⊤ 𝐹⊤ being transmitted to A Tension 𝐹⊥ A 𝐹⊥
  8. 8. © ABCC Australia 2015 6 𝐹⊥ moves to P 𝐹⊥ travels to the particle at P. 𝑣 A 𝐹⊤ being transmitted to P 𝐹⊥ Centripetal phonon enters particle at A 𝐹⊥
  9. 9. © ABCC Australia 2015 𝑣 7. Action by centripetal force The centripetal force 𝐹⊥ causes particle P to turn. A 𝐹⊥ Centripetal phonon causes particle to turn
