Skc--> *workdone nikalte Walt tada taddi nhi karni hai

*Banda h height upar Jaye to workdone by gravity=-mgh aur agar h height niche aye to workdone by gravity=+mgh(jese bhi jaye udta udta, tehelta tehlta, nachta nachta usko sirf y - axis mein displacement kitna hua USS baat se farak padta hai)

*Since displacement is frame dependent=> workdone is also frame dependent alag alag frame se alag alag dikhai degi aur kuch na diya ho to ground ke respect mein calculation krte hein

*Net workdone by common normal and tension is zero

WD by static friction can be positive negetive or zero but net workdone by static friction is always zero

*Internal forces workdone krte hein but kabhi acceleration provide nhi kr skte, acceleration humesa net external force provide krta hai

* Jabhi kabhi speed ya angular speed chaiye ho hum work energy theorem ke bare mein sochenge x(max), h(max)

*Workdone by internal forces are frame independent
Thus,
Calculation of Potential energy is frame independent

∆P.E=-WD by internal(conservative force)=wD by external force (acc=0, , होले _होले)
Thus
Mechanical energy could only be conserved if Wd by external and internal non - conservative forces are zero

❤Therefore, *wOrk energy theorem* on the bottom of the heart❤

Phir bhi :- Agar ज़मीन par zero manna hai to h height upar gravitation pE=mgh

Aur Ui=0 then spring ke pet mein pE=1÷2×kx^2 (x--> Elongation or compression from NL)

agar ♾️ par pE -->0 then q1 q2 charge agar r distance durri mein hai then unke bich pE=kq1q2/r(q1 q2 with sign put krna)

[bahadursinghsolanki]

To simulate car accident, auto manufacturers study the collisions of moving cars with mounted spings of different spings constants. Consider a typical simulation with a car of mass of 1000kg moving with a speed 18 km/h on smooth road and colliding with a horizontally mounted spring of spring constants 5.25×10^3 N m^-1. What is the maximum compressoin of the spring????

Thankuuu so
Proud to be PWIANS 🔥🔥
❤️❤️❤️❤️❤️❤️❤️

[AyushRaj-tutx]

Gvn sir, I am from lakshya jee 1.0
Sir, agar block ke karan spring h jo max compress hota h to spring apna shape regain karna chachega to kitna force spring block pe lageye ki block max distance travel kar sake(jis se spring apna shape bhi regain kar le aur block max distance bhi travel kar le).
Sir, how to find these type of force?

Sirji task diya tha na, vahi pura karne aye he...💚
Love u sir 💛💚

[seemabhagat]

Thanku sir ❤❤ you are the best teacher for students who study on YouTube. You are our life saver . I don't know but i didn't get anything in my class but after watching your lectures my backlog and concepts are crystal clear . Thanku for teaching us . Yor are the best teacher for jee

Thankyou❤ like if you agree

Saleem Bhaiya Revision Done ✅🔥💕 you're the gem Of PW

[Shaileshraj]

Saleemain present sir alot of jaisa Mai kabhi teacher nhi dekha sir ki physics feel op Aap mere liye ekk bhagwan h Orr Mai apka ekk bhakat hu aap hmm sabhi pe Aashirwad banaye rakhiye .ORR AAPKI HEALTH JLDI THIK ACHE SE .Orr JEE me selection lekar aapse Milne jarur aayunga sir ❤LOVE U SOR
