Prove That Newton 2nd Law Is Real Law Of Motion

To prove first first law we need to know both law of motion.

Prove that newton 2nd law is real law of motion. An isolated system is such that no force acts on the system. When we can show that newton s first and third law are contained in the second law then we can say that it is the real law of motion. Thus newton s 2 nd law of motion is the most basic law of motion. Thus newton s 2 nd law of motion is the most basic law of motion.

Derivation of 3 rd law. According to newton s second law of motion it means that there will be no acceleration in the body if no external force is applied. Which is newton s 1 st law of motion. This is the newton s third law of motion for a body exerting some force on another.

Newton s first law if external force applied on an object is zero then if the. An isolated system is such that no force acts on the system. Newton s second law of motion describes that when a force is applied to an object it produces acceleration in the object i e rate of change of velocity. How to prove newton s first law of motion from newton s second law of motion this physics lesson will show you how you can prove newtons first 1st law of motion using second law of motion.

Let us take an isolated system that is system isolated or free from external forces. Prove that newton s second law of motion is the real law ask for details. Consider an isolated system of two bodies a and b. Follow report by nimranclarau 21 11 2015 log in to add a comment.

Consider an isolated system of two bodies a and b. P p 1 p 2 on differentiating both sides with respect to time we wiil get d t d p d t d p 1 d t d p 2. Derivation of 3 rd law. I first law is contained in second law.

From this law f ma where f is force m is mass of object and a acceleration. Newton s third law from law of conservation of momentum result consider an isolated system consisting of two particles. This is the newton s third law of motion for a body exerting some force on another. This represents that a body at rest will remain at rest and a body in.

But do you know that the newton s second law is known as the real law of the motion. Let us prove it by showing that the newton s first law is contained in the second law.
