Beta, distance-time graph mein slope speed batata hai — seedha line matlab steady speed. Velocity-time graph ka slope acceleration dikhata hai, aur uske neeche ka area displacement nikaalne mein kaam aata hai.
Main yeh sab apne bete ko samjhate waqt uski copy par chai ke cup ka nishaan chhod aaya, jaise mere pitaji mere graphs par pencil se halchal dikhaya karte the.
Par yaad rahe, kitabon ki baat zindagi se alag hoti hai — station par tempo waale bhaiya ka speedometer kabhi straight line nahi dikhata, phir bhi wo apni manzil pahunch jaate hain.
