Question

don't you think ,time is a dimension like length after seeing this equation

Answer 1

Answer:

time is a dimension of universe

but length is a dimension of a material

Answer 2

Answer:

No.

Why did you take mass as 1kg?

The T here is the time period of the wave nature of a particle of mass m. This is as per quantum mechanics that every particle has wave characteristics.

Here T is just like time in

$s = ut + \frac{1}{2} a {t}^{2}$

It is just a parameter. Whether time is actually a dimension is debatable.

In mathematics many dimension can be assumed to exist. But that does not mean they are real. Till now there is no physical proof of time as a dimension. It may just be a perception of human mind.
