WebThe deceleration parameter in cosmology is a dimensionless measure of the cosmic acceleration of the expansion of space in a Friedmann–Lemaître–Robertson–Walker universe. It is defined by: where is the scale factor of the universe and the dots indicate … Webdefines the acceleration and deceleration rate (reference units/s2) across different target speed ranges under torque/speed control mode. As shown in Figure 1, the two parameter values related to deceleration are named 1st and 2nd linear deceleration constant.
