"Mohabbat bhi Zindagi ki tarah hoti hai
Har mod asaan nehi hota, har mod pe khushiya nehi milti.
Jab hum zindagi ka saath nehi chhodte toh
Mohabbat ka saath kyun chhode??


Physics, Hindi song and Love

Q. Show that, total work done in your love life is zero when you meet a break up.     5 marks.


Confused after reading this question? You may be thinking that when the couple was together then they have done lots of works, they went for dating in various places, they wrote lots of love letters, they talked a lot during night, they walked miles after miles together---then how the total work done can be zero?

Ok, let me prove it….



There is a Formula in physics---



Where, W=work done

F=Force applied

D= Distance covered.


You started loving her/him; it needed time to have her/him in your life. That means when you just started loving her/him you were lonely in your dream world (which has great impact in real life), after waiting for months or years you got her/him in your life, you had to made lots of wishes to get her/him, you met, you spent beautiful times and somehow you met break up----means again you are lonely, that is, you are again there where you started your journey, so total displacement = 0.

Now put the values in equation no. 1




D=your starting point and end point, i.e. your lonely life, so  you covered no distance,


W= (Prayers). (0)=0

So, if you have met break up that means you did no work in your love life----proved.

Want more explanation? here it is...

Force and Displacement,both are vectors and the equation 1 is a vector DOT product, so if we apply vector DOT product formula, the equation 1 takes the form


Where, θ is the angle, but it will not affect the result, because whatever the value of the angle you can put, Displacement is zero so total work done is zero.

Kisi bhi angle se dekhlo, woh tumhare life me hai hi nehi(whatever angle you can choose to see---she/he is not in your life) 


Generally we represent it through songs, like

Kitni aakeli thi woh raahein hum jinpe aab tak aakele chalte rahein.

Hazar raahein mudke dekhi, kahin se koi saada na aaye.
