Newtons three laws of universal dynamics are :
A body will remain stationary or in uniform motion unless acted upon by a force.
Force is directly proportional to the change in velocity .
To every force there is an equal and opposite force.
Every single object that exists obeys ALL of Newtons Laws
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
No, his three laws do not directly address work done.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Newton's First Law says that a force is required to change motion.Newton's Second Law explains the relationship between the force and the change.

Newton's First Law says that a force is required to change motion.Newton's Second Law explains the relationship between the force and the change.
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
Newton's Second Law: force = mass x acceleration
the laws of motion
The first one sets the system of coordinates (inertial). The second one gives connection between the net force and the acceleration. The third one postulates than if a first object applies some force F to a second object. The second object is applying the same force F to the first object.
All of Newton's laws are applicable to rocketry.The Second Law F=ma = dmV/dt = mdV/dt + Vdm/dt=0.The first and third law are the same equilibrium condition, No force no acceleration..
The law of gravity is not one of Newton's laws of motion. Newton's laws of motion include the first law (inertia), second law (force equals mass times acceleration), and third law (action and reaction).
