Newton's law of motion:- Based on the studies of a motion, Sir Issac Newton, one of the greatest scientist of all time had given three laws of motion, which is discussed below:

i) 1st law of Motion:-This law is also known as law of inertia, which states that, an object remains in its state of rest or of uniform motion in a straight line unless compelled to change that sate by an applied force.
In other words, it can said that the tendency of an object to remains in its state of rest of or in a uniform motion, unless it is disturbed by an external applied force.
newton's law of motion with examples:
To understand the law more deeper,lets illustrate two situation:
i)Situation I:-

But meanwhile the passenger who were at uniform motion of about 35km/hr, their body tends to remains in motion and the body gives and upward jerk to the passengers, due to change in motion, which satisfies Newton's 1st Law Of Motion.
ii) Situation II:- Have you ever observed or rode Rollar coaster, you will be able to see that when its starts moving fast it gives an backward jerk to the people riding it, in other words we can say that our body remains in rest before riding in it, and tends to remains in its state of rest, which also satisfies Newton's 1st Law.
What is Newton's 2nd law of motion?
Newton's 2nd law of motion:- Newton's 2nd law of motion states that the rate of change of momentum is always proportional to the applied unbalanced force and act in the direction of force.
newton's law of motion examples:
To understand the topic more deeply, lets illustrate a two situation which are given below:
Situation I:- Let us illustrate a car with dead battery. In our everyday life we always see when a car battery is dead, the car or a vehicle needs to be pushed to restart the engine.But the facts is that, did we asked our self , how the car starts when it is pushed with force?
Well the facts is in Newton's 2nd law of Motion, in this situation the car attains some momentum or the car engine is restarted, only due to the applied unbalanced force from behind, which satisfies Newton's 2nd law of motion.
newton's 2nd law of motion examples:
Situation II:- In our day to day life, did we ever noticed that how does our bicycle runs? Well its runs only due to Newton's 2nd law.
The fact is that, when a bicycle is at rest there is no movement in it. TO move it or to ride it, we need to apply a unbalanced force in it, thereafter it wheel starts rotating and attains some momentum, which satisfies Newton's 2nd Law.
3rd Law Of Motion :- Newton's 3rd Law OF Motion states that when one object exert some quantity of force on another object , the second object on the instant exerts a equal quantity of force on the first object in the direction opposite to the first object.
In simple words we can say that to every action done by a body , there is an equal and opposite reaction from the another body from opposite direction with same force.
To understand the topic more, lets try to illustrate two situation:-
i) Situation I:- In our daily we saw many action movies where use of gun is usual, but did we observe while firing the gun, the gun exerts some backward force, or the gun exhibits recoil while firing.Why does this happen?
Well the correct answer is from Newton's 3rd Law Of Motion, here a person fires the gun with some quantity of force and the bullet is emitted from the gun.But meanwhile the gun recoils with same quantity of force as the bullet leaves the gun in the direction opposite to the emitted bullet.. which satisfies Newton 3rd Law Of Motion.
ii) Situation II:- Let us illustrate a archer with bow and arrow, aiming to her target, stretched the bow and the emitted arrow hits the target.But did we observe how did it originally works?
Well it also works on Newton's 3rd Law of Motion. When the archer stretched the bow in backward direction, it meant some quantity of force is applied by the archer on the bow in the backward direction and on the contrary the bow emits the arrow with the same force on which the archer exerts on the bow , in the direction opposite to it, which satisfies Newton's 3rd Law.
It covers all the topics such as "newton's law of motion class 11" "newton's law of motion class 11th" "newton's law of motion 2" "what is newton's third law of motion"
Some commonly asked question:
1) Is Newton's third law applicable to mobile phone if yes then how?
Ans:- Yes, It is applicable to all smart phones, mobile phones,tablet etc.Lets us illustrate with the help of an example.
If we play game, for continuously 2hrs or more, you might that observed the following assumptions:
In case (I)
In case (II)
