Retarded vs Acceleration - What's the difference?

retarded | acceleration |

In physics terms the difference between retarded and acceleration

is that retarded is designating a parameter of an electromagnetic field which is adjusted to account for the finite speed of radiation while acceleration is the change of velocity with respect to time (can include deceleration or changing direction).

As an adjective retarded

is delayed; delayed in development, hindered; impeded.

As a verb retarded

is past tense of retard.

As a noun acceleration is

the act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.
