Question

Why we use propotionality constant in physics when we remove proportionality

Answer 1

Explanation:

We do it because that is what it means. When we say to quantities are proportional to each other, what we mean is that the variables maintain a constant ratio to each other. As an example, we can say that the circumference of a circle is proportional to its radius, since the circumference is 2π2π times its radius.
