General physics
elastic
Physics; General physics
Capable of returning to the original shape and size after having been stretched, squeezed, or bent.
eddy
Physics; General physics
A current, such as a water current or an air current, that moves in a direction that is different from that of the main current.
activity
Physics; General physics
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
Physics; General physics
A form of radioactive decay where a heavy element emits an alpha particle and some energy, thus transforming into a lighter, more stable, element.
angular frequency
Physics; General physics
A frequency, f, defined as the number of revolutions a rigid body makes in a given time interval. It is a scalar quantity commonly denoted in units of Hertz (Hz) or s–1.
angular period
Physics; General physics
The time, T, required for a rigid body to complete one revolution.
angular position
Physics; General physics
The position, , of an object according to a co-ordinate system measured in s of the angle of the object from a certain origin axis. Conventionally, this origin axis is the positive x-axis.
