In physics, elasticity refers to the property of a material that allows it to return to its original shape and size after being deformed (stretched, compressed, or bent) by an external force. When the external force is removed, an elastic material will revert to its original configuration if the deformation was within its elastic limit.

The measure of how easily a material deforms and returns to its original shape is described by Young's modulus, shear modulus, and bulk modulus, depending on the type of deformation (stretching, shearing, or compressing).

When a material exceeds its elastic limit, it can no longer return to its original shape and undergoes plastic deformation or permanent change.

Steel is more elastic than rubber. This may seem counterintuitive because rubber stretches more easily than steel, but in physics, elasticity refers to the ability of a material to return to its original shape after being deformed, not how much it stretches.

Steel has a higher Young's modulus than rubber, meaning it requires more force to deform it, but it will return to its original shape more reliably once the force is removed. Rubber, on the other hand, deforms more easily but does not return to its original shape as perfectly as steel does, especially when stretched beyond certain limits.

So, while rubber is more flexible, steel is considered more elastic in the scientific sense.

Diamond has the highest modulus of elasticity among the given materials (steel, gold, and graphite). This means it is the most resistant to deformation under stress.
Here's a brief comparison:
* Diamond: Renowned for its extreme hardness and rigidity.
* Steel: A strong and durable material, but not as elastic as diamond.
* Gold: A relatively soft metal, known for its malleability and ductility.
* Graphite: A layered material with high electrical conductivity, but not particularly elastic.
Therefore, diamond's exceptional atomic structure and strong interatomic bonds contribute to its superior elasticity and high modulus of elasticity.

Diamond is more elastic and has high modulus of elasticity than steel, gold and graphite.
Sir I am eagerly waiting for your next video on Modulus of elasticity.

[SaloniAggarwal-vu]

Thanking you sir for this vedio and continue it for 11th students..the ANS to the QUE asked... Diamond... Explanation ~ DIAMOND IS THE HARDEST SUBSTANCE ACC. TO THE DEFINITION OF ELASTICITY SO DIAMOND IS MORE ELASTIC !!! (ELASTICITY IS THE PROPERTY OF A MATERIAL TO OPPOSE A CHANGE IN THE CONFIGURATION ( Shape and size)

[tamannasantamoni]

I think c) diamond should be the most elastic material.

[kartikbhatia]

Sir, The answer is Steel (a) because it has the most lowest potential energy.

Sir in paralled circut why and how current divides. If you say that because of conductor divide so current divides so what is the divided conductors suppose 1 wire is divided into three and both of three has same no. Of electrons? We can do this by wrapping same metal wire upon it like in our house electrician wraps it. Then each have same V and Same I ??
Sir please answer i am from class 10th.🙏🥺

[SaniAbubakar-weon]

Wow sir with your videos physics has been crystal clear to me thanks you so much

[animefanclub-ju]

best teacher i love in this channel you teach best sir

[iamascientist]

Please do video on Relative motion sir

[GoodGirl-ki]

Sir please explain pascal's
principle

[shiekh]

Please make a video on stress and strain

[Sahithiallem]

Your the awesome teacher that I have ever seen ❤❤
Answer is : diamond 💎

[laxmiprasanna]

Sir, could you make a video about the nomenclature of aromatic compounds?

[SilentEyes-tq]

Thank you sir but can you do a video on motion of a car on a banked road

[dragongamingff]

Answer is diamond which is having modulus of elasticity of 1050 gigapascals❤

[DawitAlemayehu-kn]

It has been a while. How are you doing, teacher?

[MemonaAsif-bx]

Please make a timetable for academy students at 4pm to 8pm❤😊😊😊😊😊

[Uncommon_fragrance]

Sir, could you Please make a video on measures of dispersion?
It would be really helpful for us. 😢

[a.vrakshitha]

Sir please post videos on 12th physics concepts🙏
