what are the limitations of newtons second law of motion moreover when and why we use 2nd law if we have 1rst and 3rd laws also respectively...???

Hello,
Newton's second law is the relation "F=ma" i.e. the net force on an object is proportional to acceleration for a constant mass object. The application of this law is limited by the fact that the mass of an object changes as it approaches to the speed of light.
Newton's 1st law describes about inertia. Whereas newton's 3rd law says about action and reaction forces.
Each law has its own importance. The first law has introduced us with a term called inertia while the 3rd law has huge application in rocket science. The second law is extremely useful in the study of motion of bodies

Hi, The Newton 2nd law is applicable for observer in inertial frame.
Here are some cases that the Newton 2nd law fail:
1.If the mass change.
2.If the velocity approach speed/velocity of light.
3.If body experience internal force instead of external force.
Explanation
1st and 2nd cases are proved by Einstein mass energy relation and mass velocity relation. you can see this when rocket detach some parts while in space and th3 mass change for velocities near 'c'.
By the third case we say that one can't effect it's motion by exerting force by itself.

Hello friend,

The Second law of motion is as follows -

The acceleration of an object is directly proportional to the net force acting on it, and is inversely proportional to its mass. The direction of the acceleration is in the direction of the net force acting on the object.

Its Usage in daily life : -

Suppose you are pushing a cart from behind on a flat surface, then the cart will move till you pull the same and then the same will eventually stop because there is another force which is acting on the cart from opposite direction which is called as friction. So the cart will only move until the pushing force is greater than the friction applied by the road on the cart.

Hope it will help

Where does the newton second law of motion not applicable?
