Bhautik vigyan

Bhautik vigyan (Physics) ek vigyan hae jisme matter aur space aur samay kaise interact kare hae, ke baare me parrha jaawe hae. Ii energy aur force ke bhi adhyan kare hae. "Physics" sabd Greek bhasa se aais hae, jisme iske matlab "nature" hae.

Bhautik vigyan, engineering aur nawaa technology, jaise aviation, electronics aur hatyaar ke banae me jaruri hae. Mathematics me calculus ke ii kaaran se suruu karaa gais rahaa ki ii machanics, bahutik vigyan ke ek hissa, me kaam me laawa jaae sake. Bhautik vigyan ek sab se puraana parrhe waala subject hae, aur kaaheki isme astronomy bhi hae, saait sab se puraana hae.

Bhautik vigyan ke hissa

Classical mechanics

Classical mechanics me force ke adhyan karaa jaae hae aur solid, liquid aur gas ke behaviour ke bhi adhyan karaa jaae hae. Iske jaada kar ke "Newtonian mechanics" bhi bolaa jaae hae, kaaheki Isaac Newton,, laws of motion ke banais rahaa.^[1][2] Iske aur chhotaa hissa me bhi karaa jaae hae, jaise ki statics, dynamics, kinematics.^[3]

Thermodynamics

Isme temperature, pressure aur volume ke effect ke adhyan karaa jaae hae, aur energy kaise heat se transfer hoe hae. Thermodynamics ii kaaran se aage barrha ki log steam engine ke aur achchhaa kare ke kosis karat rahin.
