This strobe approximates motion at constant acceleration. When an object moving in a straight line is accelerating at a constant rate its speed is changing at a constant rate. Constant acceleration for this type of motion means that the spacing between the strobe marks changes at a constant rate. The strobe below describes a motion where the object is slowing down, going slower each second. This could also approximate motion at constant acceleration for a straight line motion.
Constant speed means that the spacing between the strobe marks is constant.
