Absolute zero | The lowest theoretical temperature a material can have, where the molecules that make up the material hae no kinetic energy. Absollute zero is reached at 0K or -273C |
Acceleration | A vector quantity defined as the rate of change of the velocity vector with time |
Activity | In radioactive substances, the number of nuclei that decay per second. Activity, A, will be larger in large samples of radioactive material, since there will be more nuclei. |
Alpha Decay | A form of radioactive decay where a heavy element emits an alpha particle and some energy, thus transforming into a lighter, more stable, element. |
Alpha Particle | A particle, a, which constits of two protons and two neutrons. It is identical to the nucleus of a helium atom and is ejected by heavy particles undergoing alpha decay |
Amplitude | Measures the amount of energy a system has |
Angle of incidence | When a light ray strikes a surface, the angle of incidence is the angle between the incident ray and the normal. |
Angle of reflection | the angle between a reflected ray and the normal |
Angle of refraction | the angle between and refracted ray and the line normal to the surface |
Angular acceleration | A vector quantity, a, equal to the rate of change of the angular velocity vector with time. It is tipically given in units of rad/s squared |
Angular displacement | The net change, (-), in a poin't angular position, (/). It is a scalar quantity |
