Newton's Second Law of Motion, also known as the Law of Acceleration, is one of the three fundamental laws of classical mechanics formulated by Sir Isaac Newton in the late 17th century. This law describes the relationship between the force applied to an object, its mass, and the resulting acceleration it experiences. It can be mathematically expressed as follows:
F. = dp/dt. When mass is constant, the equation becomes: F = m a
Where:
F is the net force acting on the object (measured in Newtons, N),
m is the mass of the object (measured in kilograms, kg),
a is the acceleration of the object (measured in meters per second squared, m/s²).
In simpler terms, Newton's Second Law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This means that if you apply a greater force to an object, it will accelerate more, and if the mass of the object is larger, it will require more force to achieve the same acceleration.
This law has numerous real-world applications and is fundamental in understanding how objects move under the influence of forces. It is essential in the fields of physics, engineering, and many other scientific disciplines that deal with motion and dynamics. Let's see how we can apply Newton's 2nd law of motion to the Chandrayaan 3 Launch.

Ball of 1kg will gain more velocity because it has lower mass and a ball with 2kg have more momentum because it has more mass
Good teacher
For class 9 students you can write rate of change of momentum as m(v-u)/t or mv-mu/t instead of delta p/ delta t
Thanks
ok brother but why ru saad?
Ball 1 will gain more velocity and ball 2 will gain more momentum as momentum is directly proportion to mass
First answer is correct. Try 2nd question again!
@@ManochaAcademy 1. Ball 1 will gain more velocity as velocity is inversely proportional to mass
(More mass less velocity
And less mass more velocity )
2. Ball 2 will have more momentum as ball 2 has more mass and momentum is directly proportional to mass .
@@ashishkumarchaudhary5839 No, momentum = Mass * Velocity , and in this case mass of 2nd ball 2 times but also dv/dt = 0.5 times. 2*0.5=1 So, momentum of both the balls will be same. -----If I am Correct.
@@bhoreralo224 yes bro you are actually right , now i got it !
Thnx for your reply
Less mass means less inertia so that means if the same force is applied on two bodies of different masses , the lighter one will move faster. Now let’s say body A being the lighter one gained velocity of 20m/s and body B being the heavier one gained half its velocity I.e 10 m/s now, if we substitute these values in the formula for momentum we find that both of them have same momentum. But generally speaking heavier bodies have larger momentum.
Ball 1 will have more velocity as it has less mass and ball 2 will have an greater momentum as p=mv and mass of ball 2 is greater
1. Ball 1 will gain more velocity as velocity is inversely proportional to mass
(More mass less velocity
And less mass more velocity )
2. Ball 2 will have more momentum as ball 2 has more mass and momentum is directly proportional to mass and velocity .
Both will have same momentum since ball 2 has more mass but less velocity so if same force is applied then the f=dp/dt=(p2-p1)/(t2-t1) now initial P1 momentum is zero as ball was at rest (consider) and t2-t1 is simply time t taken since t1 was 0(initial time) so f=P2/t for both balls now since f,t are same for both balls then P2=ft will be momentum for both balls but mass and velocity would be different, so ball 1 p =ball 2 p i.e. p¹=p² so m¹v¹=m²v² now putting value for m¹ and m² (mass of 1 and 2 ball as given in the question) 1v¹=2v² so v¹=2v² now see mass of ball 2 is 2(mass of ball 1) but velocity of ball 1 is 2 times the velocity of ball 2 so this causes balance in momentum as one has double mass and another double velocity so this causes equal momentum, please correct me if I'm wrong somewhere
@@harjassingh1385 Absolutely right bro !👍
@@ashishkumarchaudhary5839hey can u tell me the diff between d and delta or its the same
Ball 2 will gain more velocity and momentum , since P=mv and further P is directly proportional to v and m , so momentum and velocity is more when mass is more.
Ball 2 has more mass(2kg).
Therefore, BALL 2 has MORE velocity and momentum. 😊
Thank you.
For the rocket propulsion case,F=v(dm/dt) is applicable..
Both the balls will have same momentum since force and time is same for two balls and force is rate of change of momentum..
Ball with mass 1 kg will gain more velocity as for same momentum, velocity is inversely proportional to mass.
12:51 answer first will have more velocity the second will have more momentum
The velocity of the first body will be more bcz equal forces are applied in equal amount of time so the momentum is equal but that does not mean that the two bodies will have the same velocity as momentum only says that its the "motion of a body" and velocity is inversly proportional to mass of the body so obviously the velocity of the first body will be more.......just trying to clear my confusion with so much of typing 😅 let me know if im wrong pls !
Crt
both have same momentum. Let's take momentum of first and second as p1, p2. In the first case, F=dp1/dt
second case, F=dp2/dt then,
dp1=Fdt
dp2=Fdt
is it correct?🤔😄
Thank you so much sir for your wonderful explaination,I am now clear about the Newton's second law sir
You are most welcome!
Awesome Sir. Your videos are just amazing. Ball 1 will have more velocity and will gain more momentum.
Wrong answer.
Ball 2 will gain more velocity and momentum , since P=mv and further P is directly proportional to v and m , so momentum and velocity is more when mass is more.
Ball 2 has more mass(2kg).
Therefore, BALL 2 has MORE velocity and momentum. 😊
Thank you.
QUESTION 1 : Ball 1 will have more velocity because velocity is inversely proportional to mass
QUESTION 2 : Both ball will have same momentum as it is directly proportional to [ MASS and VELOCITY ] ( ball A as mass 1kg but velocity is more as momentum increase and in ball 2 mass is 2kg but velocity decrease but momentum increase because of mass and hence both have same momentum )
Yeah
Ball with 1kg will gain more velocity because has less inertia against the applied force, however all balls will possess the same momentum because of interchanging of both velocity and mass.
Thank you, Professional Tutor. For me, i think both will have the same momentum but different acceleration. Ball 1 will have higher acceleration. Studying from uganda 🇺🇬
"Force does not exist physically in the same way that an object with mass does. This means that force cannot make surface contact with an object, much less push or pull it. The initial cause of all bodies in motion originates from the applied energy (E), which creates the momentum (p) necessary to make surface contact with an object, thereby enabling it to push and pull. This concept is mathematically expressed as Ep or the equation Ep = ma. Force was originally used as a placeholder by Sir Isaac Newton because he did not know the true nature of this Force." ~ Professor Guadalupe Guerra from Laredo, Texas c/s
Sir post video on why chandrayaan take so long to go moon,even we have a technology were we could reach it in couple of days
Because moon moves 156m/s
If both balls experience the same force for the same amount of time (impulse), the lighter ball (1 kg) will have more velocity, because acceleration is inversely proportional to mass according to Newton's second law:So, for the same force, the lighter ball will accelerate faster, leading to a higher velocity.
Momentum, on the other hand, depends on both the mass and velocity. Even if the lighter ball has a higher velocity, the heavier ball (2 kg) could have more momentum because of its greater mass. Since momentum is the product of mass and velocity, it's possible that the heavier ball, despite its slower velocity, will have more momentum.
Summary:
If both balls are subjected to the same force for the same time:
The 1 kg ball will have a higher velocity.
The 2 kg ball will likely have more momentum due to its larger mass.
Ball 1 has more velocity because first balls mass is less as compare to second ball if mass decreases velocity increases,,,,ball 2 has more momentum because mass is directly proportional to momentum
Ball 1 will gain more velocity and both balls will have same momentum
can you please do a video on collision and its types? thanks
I've been tryjng to get this equation through my head for hours, but it just seemed too complicated. I can't believe how you explained it so easily, Thank you so much !
omg,frr, the equations were quite hard🥲😭🤌🏻
Thanku sir very well teached I was having doubt in this you cleared it
It's my pleasure
First ball will have more velocity and the second ball will have more momentum because p=mv
Thank you sir for the videos. They really make my concepts clear.
Answer of the homework question
Ball 1 will have more velocity and both the balls will have same momentum
Super explanation sir 😄😄 I got clarity about the Newton's second law of motion
Great 👍
Sir this is my first watching of your videos related to class 11 concepts Thanks a lot sir 🙏 And Please start making videos on class 11 sir I will also be glad
We have already uploaded few Class 11 videos of Physics, Maths and Biology. We will be uploading more videos! Stay tuned ...
The first ball will gain more velocity but momentum of both the balls will be same as the mass of second ball is more than of the first ball.
The ball with smaller mass will fell first because its velocity is higer compare to the other ball whose mass is bigger. 🎉
First ball will have more velocity and both the balls will have same momentum.
Super! Correct ✅ answer
Best example ever given 😮😮😮😊😊😊
This is very good thank you continue to the future .education of class 11 and 12 come you
Thanks a ton! We are uploading videos of Class 11 and 12. So stay tuned!
Ball 1 will gain greater amount of velocity. And two balls will gain same momentum.
Super correct!
@@ManochaAcademySir, would you like to create videos based on NCTB textbooks for Bangladeshis. I think that will do greater than Udvash or 10 minute school or other educational online platforms of Bangladesh.
I am in class 10th please solve this doubt.....
Sir how the particles which has shorter wavelength scatter the white light differently and same Ques for dust particles
1st ball will have more velocity and both 1st and 2nd ball will have the same momentum.
Thank you Sir you have cleared my all doubts 😊
Most welcome 😊
you are amazing teacher sir
Thanks a lot! Do share our channel with your friends!
Very nice and very good explanation sir🎉
Thanks a ton!
Sir the first ball will have more velocity and the second ball will have more momentum
First answer is correct. Think again about 2nd question. If same force is applied for same time, what will be the momentum of the 2 balls?
Ball 1 gain more velocity, and bot of momentum is the same
The ball which has 1kg will gain more speed and second ball will have more momentum as f= mv

If you want the explanation then comment
Yes I want explanation
No doubt, SIR ISAAC NEWTON - A Christian experimental Physicist, have contributed great great ideas in Physics and Mathematics, which no one does ever on this earth. And SIR ISAAC NEWTON'S law of force clearly specifies how to measure force and it is the real law which explains other two laws in a relastic way. All modern day space technologies are based on NEWTON'S laws. He is the one called father of Classical Physics.
Newton has made great contributions in the field of Physics and Mathematics!
