11. He acknowledged the contribution of the Pythagoreans and pointed to examples of relative motion . 12. How can this difference be due to their relative motion ? 13. These time varying magnetic fields can be caused by relative motion between two objects. 14. He called this the " principle of relative motion ". 15. The relative motion or tendency toward such motion between two surfaces is resisted by friction. 16. Temperature and relative motion speed can also affect friction. 17. The relative motion between two plates is also described by the rotation about an Euler Pole. 18. Introduce a lab frame in which an observer can measure the relative motion of the particle. 19. Is a device to permit constrained relative motion between two parts, typically rotation or linear movement. 20. Extensional faulting due to relative motion between the accretionary prism and the volcanic arc may occur.
