Calculating Contact Forces Between Two Blocks Using Free Body Diagrams

This physics video tutorial explains how to calculate the contact force between blocks using free body diagrams. It discusses how to determine the amount of force exerted by a block on another block using Newton's Third Law of Motion which states that for every action force, there is an equal but opposite reaction force. This video contains two practice problems of calculating the contact force between two blocks with and without kinetic friction.

Sir, thank you so so so much. Literally this 11 minute video did more for me than my physics teacher ever has.

[@TheFlamingPig]

truther!

[@michaelhammer1550]

Contact force always feels sort of imaginary to me, this clears it up and makes more sense.

[@siddharthrawat8729]

Loved it ! Provides a systematic way of study.

[@guilhermelembi]

You're a god. Thank you.

[@koyyanaanuradha4181]

A perfect explanation on contact forces
Very keen examples.
Thank you sir.

[@Ali_Pxll]

هذا اسطورة, يشرح كل شيء

[@ryguy2368]

Thank you so much. Literal life saver

[@dromotropic]

This was really helpful!
Thanks for the video!
Love from India!

[@eliaslisikh985]

Yo whenever I am confused about anything science related in school, you always pull through. Thank you so much!

[@nagalsri]

Dude thank you soo much I understood physics coz of u hats off ;)

[@michelleding9601]

you are super helpful! i watched alot of your videos and now I understand everything

[@kumaripremlata6147]

Thanks Very Informative 👍

[@snick9314]

For finding acceleration a straightforward equation I personal find easier to digest is
Applied force - (Mass x gravity x coefficient of friction) / Mass

[@benwalters6740]

So only if there’s friction? If there isn’t then it’s just f/m =a

[@Gladiator-wy5qb]

Thanks a lot 😁😁😁
You are a vey good Tutor👍

[@mathijslewyllie9419]

Thank you for the clear explanation! Very interesting.

[@dantecata8780]

Thank you for the video, it was incredibly helpful!

[@JamesBrodski]

Great video. Thanks for making it!

[@fuckinggoddickpile1437]

You have the physics course i have ever seen, you are much better than my physics theacher at the university😊

[@Nickelicious7]

Thanks man, such a clear explanation

[@her_honey9715]

Wow thanks a lot man ! Can u like make some questions like this or link us to a free website which includes these kind of questions please !

[@bhavanpatnayakuni9029]

u can do these problems from hcv or master the ncerte physics

[@aqmi]

Thank uuuu so much !

[@arbitrarilyentertainment8553]

Thank you very much!

[@LoneWolf-ky1nl]

Thank you very much it helped me out alot🥰🥰😇

[@indurur3174]

You're god. Thanks a lot for this explanation🖤

[@lukeshieldsnature]

Very helpful thanks

[@bavasriravichandran7014]

Thanks very much

[@Niseryusei]

شكررررررا يا سيدي

[@OliverGomes]

Very helpful ! Thanks a lot

[@scoopduna]

Please dear God show the directions

[@meliodasmama450]

U r the best buddy😊😊

[@mirsoatovxayitbek1080]

Perfect😍,could you give us some resources from which we can practice, i am from Uzbekistan

[@matthewbadilla1631]

Thank you

[@rede_neural]

Why is it that a little bit of force is "lost"? If we divide this system into even more blocks, the contact force would gradually become smaller at every pair of blocks, right?

[@priyamvadapriyam9415]

What if the blocks are stacked on one another ???? Please provide a solution for that....even a hint

[@revolverfx]

priyamvada priyam
Sum of the forces in the Y direction. You just use the same method but in a different axis.

[@jimkeen7674]

If they're stacked on top of each other, the contact force is simply the weight (mg) of the top block. This changes if there are more than two blocks. If there are more than two, the contact force between each pair of blocks is the sum of the weights of the top block and all the blocks above it.

[@sanjay_sanju06]

Thanks❤️

[@bowenying2391]

Oof there was a question on my AP Physics 1 test like this, I should have watched this video....

[@jimhalpert9803]

F

[@caseykang6570]

the content is great. But it would be even better if someone bought him a better microphone... i have to turn the volume up to max to hear him.

[@chelseafredelin8166]

Can do explain the questions on 2020 AL essay question (01) in Sri Lanka AL exam paper
Please 😢

[@MBcollegeofmathsandengineering]

Why does the frictional force on mass 1 equal that on mass 2?

[@user-vh2xi1jo2r]

tnx rly helpfull

[@vikasraina4427]

Then what is 20N force applied by 5kg object ?

[@hussamsakkijha4748]

4 m/s²

[@suryarb4843]

Awesome

[@cowgate]

Your videos are dope!

[@xandroyoung5525]

Dude whats the formula called something like this "a certain force accelerates a 3.6kg by 1.4m/s². What Would be the acceleration of 2.2kg mass when the same force acts on it"

[@MeetaJoshiArtsCrafts]

Where do we include friction between ground and block?

[@jimkeen7674]

That was the f sub k he was writing the second problem. The first problem did not include friction.

[@MeetaJoshiArtsCrafts]

@@jimkeen7674 Thanks.

[@skullhunter2711]

Thanks

[@M.MXEDITZ]

w guy thank you so much my teacher is jealous

[@alifajmi9699]

Why isnt Fc have same direction as F

[@cameronharris1660]

Do I need to know this for GCSE?

[@revolverfx]

Cameron Harris
Loool no fam. This is too complicated for GCSE Physics. This is what you learn for A level

[@rudasheikh4843]

Wow 😍😍

[@burakoerdem]

I did not physics and also ı did not like while listen to you!! thanks a lot from Turkey.

[@noraalkhateeb8362]

Are u god

[@motishimelis5604]

Any one in 2024😊

[@user-rj8zr5qb1h]

u hv more thn 6 million yet u can't spend some money for micke

[@JGMO04]

yo what about friction?

[@Ajmalnerd]
