oorja (angrezi:Energy) se tatpary hai ki- "kisi vastu men kary karane ki jo kshamata hoti hai, use vastu ki 'oorja' kahate hain. oorja ek adish rashi hai aur isaka matrak 'jool' hota hai. vastu men jis karan se kary karane ki kshamata a jati hai, use hi oorja kaha jata hai. oorja samajik aur arthik vikas ke lie tatha kisi bhi desh men manav jivan ki gunavatta men sudhar lane ke lie atynt mahattvapoorn hai. kisi bhi desh ki sampannata is bat par bhi nirbhar karati hai ki us desh men oorja ke srot kya-kya hain aur unaka kitana upayog ho raha hai.

kary evn oorja

kee prakar ke upayon dvara oorja ko ek roop se doosare roop men badala ja sakata hai. in parivartanon men oorja ki matra sarvada ek hi rahati hai. usamen kami nahin hoti. ise oorja ka avinashita ka siddhant kaha jata hai. jaisa ki kaha gaya hai ki- "kary kar sakane ki kshamata ko oorja kahate hain", parntu sari oorja ko kary men parinat karana snbhav nahin hota. isalie yah kahana adhik upayukt hoga ki "oorja vah hai, jo utani hi ghatati hai, jitana ki kary kiya jata hai." is karan oorja ko napane ke ve hi ekak hote hain, jo kary ko napane ke hote hain. yadi ek kilogram bhar ko ek mitar ooncha uthaya jata hai to prithvi ke gurutvakarshan ke viruddh ek vishesh matra men kary karana padata hai. yadi isi bhar ko do mitar ooncha uthaya jaye athava do kilogram bhar ko ek mitar ooncha uthaen to donon dashaon men pahale ki apeksha duguna kary karana padata hai. isase prakat hota hai ki kary ka pariman us bal ke pariman par, jisake viruddh kary kiya jae aur us doori ke pariman par, jis doori dvara us bal ke viruddh kary kiya jae, nirbhar rahata hai aur in donon parimanon ke gunanaphal ke barabar hota hai.
