Chapter ki baat
Physics kya hai? - Nature ko samajhne ki science. Galaxy se lekar atom tak sab yahi aata hai.
Scientific method - Pehle kuch dekho, phir guess karo, phir experiment karo, phir rule banao. Galileo ka naam famous hai isme.
Classical vs Modern - Classical matlab Newton wala (badi cheezein). Modern matlab Einstein wala (chhoti cheezein aur tez speed).
Conservation laws - Energy kabhi khatam nahi hoti. Mass bhi nahi. Ek form se dusre mein badal jaati hai.
