Retardation
Encyclopedia
Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays. In particular, it can mean:
In engineering
- Negative accelerationAccelerationIn physics, acceleration is the rate of change of velocity with time. In one dimension, acceleration is the rate at which something speeds up or slows down. However, since velocity is a vector, acceleration describes the rate of change of both the magnitude and the direction of velocity. ...
in mechanics (i.e. rate of decrease of velocity) - Retardation factorRetardation factorIn chromatography, the retardation factor is defined as the fraction of an analyte in the mobile phase of a chromatographic system.. In planar chromatography in particular, the retardation factor is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by...
in chromatography - Retarded potentialRetarded potentialThe retarded potential formulae describe the scalar or vector potential for electromagnetic fields of a time-varying current or charge distribution. The retardation of the influence connecting cause and effect is thereby essential; e.g...
