Physics key terms 2

1. error of measurement due to readings that vary randomly with no recognisable pattern/trend/bias (6, 5)
4. rate of transfer of energy (5)
8. potential difference/current (10)
9. The potential difference across a metallic conductor is proportional to the current, provided the physical conditions do not change (4, 3)

2. energy transferred to where it is wanted when it is wanted (6, 6)
3. measure of an angle defined such that 2π radians=360° (6)
4. the difference in distances between two coherent sources to an interference fringe (4, 10)
5. deformation of a solid beyond its elastic limit (7, 11)
6. time for one complete cycle of a wave to pass a point (6, 2, 1, 4)
10. error of measurement due to the readings that systematically differ from the true reading and follow a pattern/trend/bias (10, 5)
