Final answer:
The statement about the diverging advance approach is unclear in the context of physics, but the given examples relate to concepts of motion, velocity, and acceleration, and even the theory of relativity as per the speed of light.
Step-by-step explanation:
The statement regarding the diverging advance approach does not appear to be related to physics directly, and as such, provides insufficient context for a clear answer in the field of physics. However, multiple statements are provided from which we can infer that the original question may be related to the concepts of motion, velocity, and acceleration within physics.
For example, a car moving on a straight road at a constant speed indicates uniform motion, which means there's no acceleration since velocity is constant. This is true as long as the motion does not change its speed or direction.
In contrast, a ship moving in the forward direction and then decelerating also demonstrates a physics concept, where deceleration implies negative acceleration, assuming deceleration refers to slowing down in the context of the question. Lastly, the reference to the second postulate of relativity involving light speed c and classical velocity addition suggests the topic is delving into more advanced physics principles associated with Einstein's theory of relativity.
