The number of joules absorbed from ionising radiation per kilogram of tissue, measured in Greys (Gy)
Absorbed dose
1 of 9
An electrical component used to keep charge separated and usually consisting of a pair of electrical conductors separated by a thin layer of insulator
Capacitor
2 of 9
A change in observed wavelength due to the relative motion of source and observer
Doppler shift
3 of 9
The distance from the centre of the lens to a focal point, for a thin lens
Focal length
4 of 9
The tendency of any stationary object to remain stationary or of any moving object to continue with the same momentum (Newton’s first law)
Inertia
5 of 9
The property of a material making it easy to hammer or press a sheet into a required shape
Malleable
6 of 9
A mass (bob) on the end of a string that can oscillate back and forth in simple harmonic motion
Pendulum
7 of 9
The ratio p.d./current for a circuit component, measured in ohms
Resistance
8 of 9
Tensile forces are stretching forces. An object is in * when two forces act on it in opposite directions to make the object stretch along the line of action of the forces
