Across
  1. 3. Study of motion and energy
  2. 6. Change in velocity
  3. 9. the throwing back by a body or surface of light, heat, or sound without absorbing it.
  4. 10. Change in position
  5. 11. Measured of how far an object traveled
  6. 12. Measure of distance over time
Down
  1. 1. Slowing down
  2. 2. have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum
  3. 4. In materials science, dispersion is the fraction of atoms of a material exposed to the surface. In general: D = NS/N. where D is the dispersion, NS is the number of surface atoms and NT is the total number of atoms of the material.
  4. 5. Push or pull
  5. 7. Means “change in”
  6. 8. having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves
