To chaliye aapka jaada time naa lete huye aaj ka part-1 start karte hai.
Speed , distance and time part-1
Iss part me hum kya-kya sikhenge ?uske liye humane ek list banayi hai. Jo iss prakar se hai-:
• What is the defination of distance and its unit ?
• What is the defination of time and its unit ?
• What is the defination of speed and its unit ?
• Relation between speed , distance and time.
• Some important tips.
• What is the defination of distance and its unit ?
Distance दुरी ( duri ) kya hota hai ?
Hum sabhi jaante hai ki , agar koi object (वस्तु) chal rahi hai to iss object ki position time ke saath-saath change hoti rahati hai. To issi prakar se hum iss object ki distance ki defination ko define kar sakte hai.
Defination of Distance-:
Kisi gatimaan vastu (moving object) dwaara tay (travel) kiye gaye maarg (way) ki lambai (length) ko uss vastu dwaara chali gayi distance kahte hai.
Normally issko iss ke first letter D se denote karte hai.Aayiye iss ko ek example se samjhte hai.
Ex-: suppose kariye ki , ek car , point A par hai phir kuch time ke baad ye chal kar point B par pahuch jaata hai to point A se lekar point B tak ki length ko car dwaara travel ki gayi distance kahte hai.
(See the figure-2)
Unit of distance-:
Generally issko kilometer (km), meter (m), centimeter (cm) , millimeter (mm) etc. me measured kiya jaata hai isliye ye hi isske unit hai.

• What is the defination of time and its unit ?
Also read-:
time (समय) humari life ka very important part hai. Hum koi bhi kaam ko kare uss kaam ko karne me time jarur lagata hai. Aap "so" (sleeping) rahe hai to , time lagta hai. Aap iss topic ko read kar rahe hai to iss se complete karne me kuch time lagega . Means aap kuch bhi karo time jarur lagega. To iss hissab se time ka defination ye huaa ki , "Kisi bhi work ke first step se second step me jaana hi time kahalata hai."
Means time hume ye batata hai ki , koi work huaa ya nahi.
Means time hume ye batata hai ki , koi work huaa ya nahi.
Time ko hum isske first letter T se denote karte.
For example-:
Figure-1 me car ko point A se B tak jaane me kuch time lagta hai.
Unit of time -: Time ka unit second , minute , hour , day , week , month and year hota hai.
• What is the defination of speed and its unit ?
Speed चाल (chaal) kya hota hai ?
Hum sabhi daily road par car , bus, bike , scooter etc. anek prakar ke vehicles (vaahan) ko chalate huye dekhate hai. In sabhi ki ek speed valuable hoti hai. Ye sabhi ek speed ke saath aage chalte hai.
Kisi ki speed jaada (more) to kisi ki speed kam (less) hoti hai. Aayiye iss se defination se samjhte hai.
Defination of speed-:
Kisi moving (gati) karta huaa object, per unit time me jitana distance travel ( tay) karta hai, usko uss moving object ki speed kahte hai.
Ab per unit time kahane ka kya matlab huaa ?
per unit time ka matalab ye huaa ki moving object jitana distance travel karega to iss distance ko cover karne me kuch time lagega. Issi time ko hum distance se divide karenge. Ye divide karna hi per unit time kahalaata hai.

• Fast calculate square of numbers ending with 5
Aayiye issko bhi ek example se samjhte hai:
Example: Suppose karte hai ki , ek car 2 hour me 60 kilometer jaata hai to , Distance = 60 km.
time = 2 hour
Isliye speed = 60 km/ 2 hour
= 3 km/h
Unit of speed-:
Speed , two quanties (distance and time ) par depends karta hai isliye iska unit inn two quanties se related hoga. To iss prakaar se kilometer/hour (km/h) , mile/hour , meter/second (m/s) etc. iske unit hai.

• Relation between speed , distance and time -:
Speed , distance and time ke beech 3 relations hai. Jo iss prakar se hai -:
(1). Speed = Distance/Time
Ye relation hume batata hai ki , agar question me Distance and Time diya ho to iss relation ka use kark hum speed , calculate kar sakte hai.
(2). Time = Distance/Speed
Ye relation hume batata hai ki , agar question me Distance and Speed diya ho to iss relation ka use kark hum Time , calculate kar sakte hai.
(3). Distance = Speed×Time
Ye relation hume batata hai ki , agar question me Speed and Time diya ho to iss relation ka use karke hum Distance calculate kar sakte hai.

To friend Aaj ke part - 1 me bas itana hi. Iske aage hum next part me jaanenge . I hope ki ," aapko aaj ka part achhe se samjh aaya hoga".Also read-:

• Some important tips
Iss topic se related question ko jab hum solve karenge tab hume kuch important tips ko jarur yaad rakhana hoga:
(1). Sabse pahle diye huye question ko bahot hi dhyaan (carefully) se 3-4 baar read kare.
(2). Question me kya-kya diya hai ? usko maalum kare. Jaise-: Distance, time and speed.
(3). Ye jarur maalum kar lijiye ki qestion me diye huye distance , time and speed sabhi ki unit same hai ya nahi.
Agar same nahi hai, to issko convert karke same kar lijiye.
Jaise-: Agar question me speed ki unit km/h diya ho to distance ki unit km and time hour me hi hona chahiye. Agar aisa nahi hai to issko convert Kariye.
(4). Agar question me speed, distance and time me se koi two ( S and D or S and T or D and T ) diya ho to uppar diye 3 relations ka use karke hum third ( S , D and T me jo naa diya ho) usko maalum karenge.
Agar aapko kuch puchana hai ya aapko koi doubt hai to aap niche diye comment box , contact form ya humare Facebook page par massage karke puchh sakte hai. Hum aapki puri help karne ki koshish karenge.
