Force is not DERIVED  but defined by Newton's first law.

According to Newton's first law - "Every body continues to remain in its state of rest or the state of uniform motion in a straight line unless an external unbalanced force acts on it"

 

So, from thiswe can define force as that external cause which changes or tends to change the state of rest or the state of uniform motion of a body in a straight line.

According to Newtonian Physics , the first law of motion defines Inertia n Force as anything that changes or tends to change the state of rest or uniform motion of an object along a straight line . We can derieve the equation of force from the second law of motion as f = ma .
