Definition
What is it?
Something is 'short' when its length or height is less compared to something else, or less than what is expected. It means it doesn't extend very far from one end to the other. We use 'short' to describe objects, distances, or even time.
Simple Example
Quick Example
Imagine you have two pencils. One pencil is brand new, and the other has been sharpened many times. The pencil that has been sharpened many times is shorter than the new one because its length has decreased.
Worked Example
Step-by-Step
Let's compare the height of two friends, Riya and Rohan.
Step 1: Riya measures her height as 120 cm.
---Step 2: Rohan measures his height as 110 cm.
---Step 3: To find out who is shorter, we compare their heights: 110 cm is less than 120 cm.
---Step 4: Therefore, Rohan is shorter than Riya.
Answer: Rohan is shorter.
Why It Matters
Understanding 'short' is basic for Physics when measuring distances and sizes, and for Engineering when designing structures or parts. Architects use it to plan buildings, and even fashion designers use it to create clothes. It's a fundamental concept for comparing and measuring things around us.
Common Mistakes
MISTAKE: Thinking 'short' always means small. | CORRECTION: 'Short' means less in length or height, but it's always a comparison. A 'short' building might still be quite tall, just shorter than another building.
MISTAKE: Confusing 'short' with 'thin'. | CORRECTION: 'Short' refers to length or height (how long or tall something is), while 'thin' refers to width or thickness (how wide or broad something is). A short stick can be thick.
MISTAKE: Not having a reference point when saying something is 'short'. | CORRECTION: Always think 'short compared to what?' or 'short for what purpose?'. For example, a 10 km journey is short for a train but long for a walk.
Practice Questions
Try It Yourself
QUESTION: A school bus is 10 meters long. A car is 4 meters long. Which vehicle is shorter? | ANSWER: The car is shorter.
QUESTION: Your elder brother's cricket bat is 90 cm. Your younger sister's toy bat is 45 cm. How much shorter is the toy bat than the cricket bat? | ANSWER: The toy bat is 45 cm shorter (90 cm - 45 cm = 45 cm).
QUESTION: A rope is cut into two pieces. One piece is 2.5 meters long, and the other is 180 cm long. Which piece is shorter? (Hint: Convert units to be the same). | ANSWER: The piece that is 180 cm long is shorter. (2.5 meters = 250 cm; 180 cm < 250 cm).
MCQ
Quick Quiz
Which of these objects is likely to be described as 'short' compared to a typical Indian railway track?
A highway
A river
A football field
The distance from Delhi to Mumbai
The Correct Answer Is:
C
A football field (around 100 meters) is very short compared to a railway track, which can be thousands of kilometers long. Highways, rivers, and the distance from Delhi to Mumbai can be very long.
Real World Connection
In the Real World
When you buy clothes online, you often check if a kurta or a pair of jeans is 'short' for your height. Construction workers use measuring tapes to make sure a wall or a pillar is not too short, ensuring the building is stable. Even when buying vegetables, you might pick a 'shorter' brinjal or cucumber if you need a smaller portion.
Key Vocabulary
Key Terms
LENGTH: The measurement of how long something is from end to end. | HEIGHT: The measurement of how tall something is from bottom to top. | COMPARE: To look at two or more things to see how they are similar or different. | MEASURE: To find the size, amount, or degree of something using a tool.
