Definition
What is it?
Position tells us where something is located in space or relative to other objects. It helps us describe the exact place of an object, person, or point. Think of it as giving an address for anything around you.
Simple Example
Quick Example
Imagine your school bag. If you say, 'My school bag is under my study table,' you are telling its position. If you move it to 'on top of my bed,' its position has changed.
Worked Example
Step-by-Step
Let's find the position of a cricket ball on a field.
1. First, we need a starting point, like the middle stump at one end of the pitch.
2. Next, we need directions. Let's say the ball is 10 meters towards the boundary from the middle stump.
3. We also need to know if it's straight or to the side. So, let's say it's 10 meters straight out from the middle stump, towards the long-on boundary.
4. This description, '10 meters straight out from the middle stump towards long-on,' tells us the exact position of the cricket ball.
--- The position of the cricket ball is 10 meters straight out from the middle stump towards the long-on boundary.
Why It Matters
Understanding position is super important in many fields. It's used by pilots to fly planes safely, by ISRO scientists to track satellites, and by delivery riders using GPS to find your address. Learning this helps you understand maps, directions, and even how games like chess work.
Common Mistakes
MISTAKE: Not having a reference point (starting point) when describing a position. | CORRECTION: Always state position relative to something else (e.g., 'next to the TV,' 'behind the car,' '5 meters from the door').
MISTAKE: Using only one direction when more are needed (e.g., just 'north' when 'north-east' is more accurate). | CORRECTION: Use precise directions and distances to make the position clear and unambiguous.
MISTAKE: Confusing the object itself with its position. | CORRECTION: Remember, the object is the thing, and its position is where that thing is located.
Practice Questions

QUESTION: Your friend says, 'My water bottle is on the table.' What is the reference point for the water bottle's position? | ANSWER: The table.
QUESTION: Describe the position of the sun in the sky during midday. | ANSWER: The sun is directly overhead or at its highest point in the sky.
QUESTION: Your house number is 15, and your friend's house is number 20 on the same street. If you are standing at your house, how would you describe your friend's house's position relative to yours? | ANSWER: Your friend's house (number 20) is 5 houses away from yours, further down the street.
MCQ
Quick Quiz
Which of these best describes the position of a book?
It is a story book.
It is red in colour.
It is on the top shelf, next to the window.
It has 200 pages.
The Correct Answer Is:
C
Option C tells us exactly where the book is located (on the top shelf, next to the window), which is the definition of position. The other options describe what the book is or its features, not its location.
Real World Connection
In the Real World
When you order food using an app like Swiggy or Zomato, the app uses your phone's GPS to find your exact position. This information helps the delivery person know where to come and drop off your order. Without understanding position, these apps wouldn't be able to connect you with your favorite food!
Key Vocabulary
Key Terms
LOCATION: The specific place where something is found | REFERENCE POINT: A fixed point or object used to describe the position of another object | DIRECTION: The path an object moves or is oriented (e.g., north, south, left, right) | DISTANCE: How far an object is from a reference point

What to Learn Next
Now that you understand what position is, you can learn about 'Motion.' Motion is all about how an object's position changes over time. It's a natural next step to see how things move from one position to another!
