Every thing heats up... yes..... everything.... heat is wonderful.... when anything gets into contact with a hot object it heats up. But this excess heat can be good, bad or even ugly.

Consider a engine. When it runs it heats up..... if it gets hotter and hotter and hotter then what will happen. Yess.... you guessed right my friend..... the engine will fail, it can bust !!!!! Thats why every engine needs a Cooling System.

Prosner uttor janar jonno amader kisu choto bishoy age jene nite hobe.
                            1.Kaj (Work)  
                                 2. Shokti (Energy)
                                    3.Khomota (Power)

KAJ (WORK)--
                    Jokon kono bostu k amra tani kingba dhakka dei tokon amra Physics ar vashay take Bol boli.
                    Ekn ai tana ba dhakka deyar fole jodi bostuti tar ager jaiga theke sore jay amra boli bostur Soron hoyece.

       Orthat bol proyoger karone bostur soron ghoteche.... ekn amra jodi bol o soron ar man jani ar ai dutor gunfol ber korte pari tobe aitai hobe kaj.
                                                   
                                               KAJ = BOL x SORON 
                                               W= F * S      ekhane W diye kaj
                                                                                 F diye bol
                                                                                 * diye gun chinno bujano hoyece.

SHOKTI (ENERGY)-- 
                               Ja thakle kono bostu kaj korte pare orthat bol proyog korte pare kingba soron ghotate pare tai sokti.
                              Tai sokti bolte amra buji ja thakle kono bekti ba bostu bol toiri korte pare . Tai bola jai kaj korar shamortho ke sokti bola hoy. Ek orthe kono bostu joto kaj korte parbe tai tar shokti.

KHOMOTA (POWER) --
                                         Proti ekok somoye orthat 1 ghonta kinba 1 min ba 1 s a kono bostu joto tuku kaj korte parbe tai oi bostur khomota.
