By the second equation of motion,
s = ut + 1/2 at 2
S is directly proportional to the time only when there is no external force acting on it.
In the absence of external force, acceleration ‘a’ of the object becomes zero and the equation of motion becomes
s = ut
Since acceleration is zero so speed ‘u’ of the object remains constant.
Hence, it can be concluded that S is directly proportional to t.

Unification: It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena.

Eg. Electricity, magnetism and light are different phenomena and have different laws of physics for each of them. These are unified under theory of electromagnetism;
