please anyone who can clearly explain .I am unable to understand this constant of proportionality and why is F=ma.

Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the accelerationof that object increases by the same factor. In short, force equals mass times acceleration.
In Physics and other branches of Science or Subjects it is applied and used to describe variables. If change in one variable is always accompanied by a change in another variable, and if the changes between the two are always related by a constant multiplier, two variables are termed as proportional to each other.

As force is directly proportional to change in momentum by time taken which means F.mv-mu/t.
F. m(v-u)/t
since v-u/t = acceleration
so,. F = ma
F. m(v-u)/t
since v-u/t = acceleration
so,. F = ma
