- Physics Ninja demonstrates how to find the tension in the strings. We draw the free body diagram for the masses and write down Newton's laws and solve for the tension and the acceleration of the blocks
THANK YOU, this clarified everything for me with these problems
Thanks for comment! Happy to help.
What a beautiful solution to a great problem.
THANK YOU SO, SO MUCH!! I didnt understand this topic when it was taught in class and later gave up for a yr but now we're doing it again and i figured I had to deal with it sooner or later. With your video, I FINALLY understood the concept and can now solve questions on my own. Really grateful, man.
That’s great to hear. Good luck on your exams! Comments like this are the reason I make videos.
Oh man this helped so much with tension problems and general. Helped me figure out solving blocks on planes too! Great explanations and breakdown
Absolute nice way of teaching
oh my god THANK YOU SO MUCH for this video. I was struggling so much but you explained it so well.
Glad it helped!
you have no idea how helpful this was, stresing over first year uni rn, this video from five years ago was a godsend
hahaha same. What's the chances of us being in the same uni?

Thank you so much! That was an extremely clear explanation. For the problem I was solving, the total acceleration was already given to me for three identical blocks being pulled to the right with a force of 55 N. It asked for the tension of a string but it's the same throughout since the blocks are identical. I got the answer now :)
Good job Lillian!
Very good explanation to teach the mathematical expressions for tension. 👍
Great explanation. Thanks for your work explaining Newton’s laws.
My pleasure!
Thanks!!! This helps so much, ur explanation was much better than my teacher’s!
daddy cracked at teaching. i appreciate u
thank you u made me believe in myself as i didnt quite since i did the same thing but u made me be confident for similar questions
awesome job! you've got this.
This was just what I needed..Thank you
Glad I could help
Great presentation. Very clear. Thanks!
Thankyou sir, I am very confused how to solve this type question but after saw your video my doubt are clear thankyou sir I am from india
good stuff bro im not even capping no cap
Beautifully explained
Omg this is the single reason ill pass my physics exam tmrw, TYSM
Superb explanation.. And thanks to answers sir
i wish you were my physics teacher
Thanks so much dude! This helped me really understand this topic!
Thank you Sir
Thank you very much
Really confused at the beginning when you made separate equations for the blocks, so I paused, and singled out all tension variable, and substituted them until they fit in block m1 equation with the Fa. Ended up as Fa = a (m1+m2+m3). Now it makes much more sense. But as you can see, as I un paused, so they somewhat the same thing. I was confused whether the tension was the same in all the ropes.
It is very useful for study and speak is very wonderful
Thank you for teaching this. It was really clear
tysm sir i was finding it difficult to solve these now i understood tysm
Love from India....Thanks a lot ! 😊
so helpful, my problem was with 4 objects and still this video helped me get all of the right answers for my question. thank you.
Awesome!! You got this.
@@PhysicsNinja now im trying to do another with two objects but im stuck
superb sir..
Made so easy:)
Thank youuuu!
Nice explanation
This was like the easiest question in my jee syllabus
Thank you so much! You literally saved me :')
Very clearly explained
Thank you so much 😭❤
You're so welcome!
Thank u so much sir well explained 😅i have a test on this next week been studying very hard ❤ I will tell all my friends about this video
Amazing Video
we love you
thanks for this amazing video...
Superb... I love physics... pls post some videos with inclined plane, free body diagram
That was beautiful
Subscribers from India ❤️❤️
U are a great physics teach and Ty so much 🌹
You just made my life a ton easier
This was great! Thanks
THANK U SO MUCH I FINALLY UNDERSTOOD THIS LESSON because my class teacher is an old man and i dont understand anything he says cuz he is missing teeth and he is half asleep while "teaching" TYSM!
Glad it helped!
In which class this topic is studied??????
Thank you!
Thank you it solved my problem❤️
Thanks 😊 from India
Thank you sir. Our sir taught us how to two boxes question and gave us three boxes question to try and i wanted to solve, from ur video I understood and solve it ❤ and Love from India ❤
Thank you
Thanks 👍👍👍👍👍 sir
amazing. thank you.
Superb sir
Thank you I lost 5 marks in my previous exam due to this.
Thank you very very much sir it helped me very much ☺️☺️
What would be the max. tension on each cable at the moment it overcomes the frictional force on those blocks? Can you assign friction coefficient and do an example?
this video saved me from failing my hw
You made this soo easy! Thankyou🤗
I'm really confused you didn't put any frictional force on the forces acting horizontal cause according to my teacher whenever there's an applied force there's going to be a frictional force unless it's frictionless,but you didn't mentioned that it's frictionless that is why I'm lost.
If the blocks have different friction constant ,so what will be the tension fore ?
Thank u soooo much!
Great❤️
Outstanding video sir.
hi, may I clarify that to solve the acceleration of the 3 blocks, you can just treat the 3 blocks as a system, then find acceleration using equation F=total mass x acceleration ?
Yes that works!
@@PhysicsNinja thanks a lot! your video really made these kind of questions so much easier to solve!
U forgot about friction? What did you specify the normal force for?
Why did u not consider force of friction acting on both blocks?
Sir I have a doubt that why did you take the tension force of 5 kg block T2 . Why it is not T1 .
By the great explanation
Thanks from India 🇮🇳

Thanks!!
God bless u sir thank u very much!❤
So nice of you
Thank u ❤️❤️
You are better than my teacher😁😁😁
❤thanks
Uh I have a question. Could I treat the 8kg and 2kg block as one thing and derive the equasion from newton's second law: 300-T2=10(a)?
oh it's really helpful for my problem. thanks.
Sir ur wonderful
Really really thxx for helping me...... 🙂🙂🙂
Simple trick:
T1:
(5+8)×300/5+8+2
13×300/15
3900/15
=260
For those who want to save some time
F=ma
That means a=f/total mass
Tension= (m1+m2)×force/total mass
(specific for the case of T1)
The pro elimination trick rocked sir 👌
What if we got the answer 59.62N as the answer?
As in:
Fa= (Ba+Bb+Bc)*a
300N=(5kg+8kg+2kg)*a
a=300N/15kg
a=20m/s^2
Tension on Tc:
Tc=Bc*(g+a)
Tc= 2kg*(9.81m/s^2 + 20m/s^2)
Tc=2kg*29.81m/s^2
Tc=59.62N
tension in the string between blocks A, B and C = 59.62 N
My question is what is the difference?
Thank you 😭❤️
is there a video about the Tension in the Strings with the friction force as well?
Thanks ninja....
Thankyou for this it helped...!
Sir if force is not given then how to find acceleration
Being from India and understood this topic from u only is such a good feeling
Thankyou very very muchh sir❤️🙏😀
Love from india❤
Why do the second two blocks have the same tension?
different strings will have different tensions, same strings have the same tension
will u plz explain me athing why there is tension t1 equal and possite tension t2
Very good video!
Did I forget the friction of the blocks with the table?
Why does the original force drop between the bodies? I've asked on physics stack exchange and my professor but no satisfactory answer so far.
If one force is exerted in the first place why does it drop towards the end of the system?
Because they don’t pull as much mass. The second only pulls 2 blocks, the third tension only pulls 1 block
can you do it for vertical suspension
Now i get it
Is there education system in foreign like indiaaa?
Hi, I am confused. For the 8kg block T1 is acting to the right and t2 is acting to the left. But why is ma= T1-t2? T1 and t2 are acting on different objects why will they be able to cancel out each other?
It's a freebody diagram. The objects are analysed in parts. t1 is pulling from the right, but the middle object is also pulling the left most object with a tension force of t2 toward the right. Acording to newton's third law, the left most object is also has to pull the middle object toward the left, hence the -t2.
Thank youuuuuuuuuuuuu
Indeed you are a physics Ninja,👏👏👏👏
An 80 N object suspended from a ceiling is pulled by a horizontal force of F, as shown in the figure. a) Find the tension in the string.
Who can help me please?
Do we need to convert kg to newton sir?
Yes you do
Thanks sir...
