People, such as pilots, who have to move quickly from lighted surroundings to night darkness use red light illuminatin. This is because
red light slows down dark adaptation.
red light is a stimulating color and tends to keep pilots and military personnel
aroused and alert.
the cones are insensitive to red light.
the rods are insensitive to red light.

Ais the answer hope this

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
