Let us derive the relation of force F = ma from Newton’s second law:

According to the Newton’s 2^{nd} Law of motion, the rate of change of linear momentum of a body is directly proportional to the applied external force and in the direction of force.

It means that the linear momentum will change faster when a bigger force is applied.

Consider a body of mass ‘m’ moving with velocity v.

The linear momentum of a body is given by:

p = mv

Now According to Newton’s 2^{nd} Law of Motion:

Force is directly proportional to rate of change of momnetum, that is

F α dp/dt

F = k dp/dt

F = k d(mv)/dt

F = k md(v)/dt

F = k ma

Experimentally k =1

F = k ma

Which is the required equation of force.

Hey it’s too good i clearly understood the law

it would be clearer if u mentioned p=mv and v/t=a and thus ma arises out,

anyways good work and thanks.
