Prove That Newton 2nd Law Is Real Law Of Motion

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.

Prove that newton 2nd law is real law of motion.

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. 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 prove it by showing that the newton s first law is contained in the second law. 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. Consider an isolated system of two bodies a and b.

Consider an isolated system of two bodies a and b. Prove that newton s second law of motion is the real law ask for details. Derivation of 3 rd law. P momentum of the whole system and p 1 and p 2 are the respective momentum of the particles.

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. Thus newton s 2 nd law of motion is the most basic law of motion. Follow report by nimranclarau 21 11 2015 log in to add a comment. Newton s first law if external force applied on an object is zero then if the.

But do you know that the newton s second law is known as the real law of the motion. 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. For an object at rest the applied force produces acceleration in the object and makes the object move in the direction of applied force. 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. An isolated system is such that no force acts on the system. To prove first first law we need to know both law of motion. Which is newton s 1 st law of motion.

Derivation of 3 rd law. Which is newton s 1 st law of motion.
