Physics key terms 2

1. energy transferred to where it is wanted when it is wanted (6, 6)
6. measure of an angle defined such that 2π radians=360° (6)
7. The potential difference across a metallic conductor is proportional to the current, provided the physical conditions do not change (4, 3)
8. rate of transfer of energy (5)
10. deformation of a solid beyond its elastic limit (7, 11)

2. error of measurement due to the readings that systematically differ from the true reading and follow a pattern/trend/bias (10, 5)
3. -continuous spectrum:continous ranges of colours corresponding to a continuous range of wavelengths, line emission spectrum -characteristic coloured vertical lines, each corresponding to a certain wavelength, line absorption spectrum -dark vertical. (5, 2, 5, 7)
4. the difference in distances between two coherent sources to an interference fringe (4, 10)
5. potential difference/current (10)
9. error of measurement due to readings that vary randomly with no recognisable pattern/trend/bias (6, 5)
