Definition
What is it?
Far describes a large distance between two points or objects. It tells us that something is not close to us or to another specific point. The opposite of far is near or close.
Simple Example
Quick Example
Imagine you are standing at your school gate. Your home is 'far' if it takes you a long auto-rickshaw ride to reach it. If your friend's house is just next door, it is 'near' or 'close'.
Worked Example
Step-by-Step
Let's find out if the grocery store or the hospital is farther from your house.
Step 1: Find the distance from your house to the grocery store. Let's say it is 500 meters.
---Step 2: Find the distance from your house to the hospital. Let's say it is 2 kilometers.
---Step 3: To compare, convert both distances to the same unit. 2 kilometers is equal to 2 * 1000 = 2000 meters.
---Step 4: Now compare 500 meters (grocery store) with 2000 meters (hospital).
---Step 5: Since 2000 meters is much larger than 500 meters, the hospital is farther from your house.
Answer: The hospital is farther from your house.
Why It Matters
Understanding 'far' is key in subjects like Geometry to measure distances and in Physics to calculate motion. It's crucial for engineers designing bridges and for AI systems in self-driving cars to know how far other vehicles are.
Common Mistakes
MISTAKE: Thinking 'far' is always a fixed distance, like 100 meters. | CORRECTION: 'Far' is relative. What is far for walking might be near for flying in an airplane.
MISTAKE: Confusing 'far' with 'big' or 'heavy'. | CORRECTION: 'Far' only relates to distance, not to the size or weight of an object.
MISTAKE: Not considering the path taken when judging 'far'. | CORRECTION: Distance is usually measured along the shortest path, but 'far' can also refer to the travel time or effort, like a long winding road.
Practice Questions
Try It Yourself
QUESTION: Your school is 3 km from your home. Your friend's house is 500 meters from your home. Which is farther? | ANSWER: Your school is farther.
QUESTION: A train travels 200 km in 2 hours. A car travels 150 km in 2 hours. Which vehicle has travelled farther in the same amount of time? | ANSWER: The train has travelled farther.
QUESTION: A delivery person has two packages. Package A needs to go 1.5 km north. Package B needs to go 2500 meters south. Which package is going to a location farther from the starting point? | ANSWER: Package B is going to a location farther (2500 meters = 2.5 km, which is more than 1.5 km).
MCQ
Quick Quiz
Which of these objects is likely to be 'far' from your classroom?
Your desk
The blackboard
The principal's office
Your textbook
The Correct Answer Is:
C
Your desk, blackboard, and textbook are all typically very close to you in a classroom. The principal's office is usually in a different part of the school building, making it 'far' relative to your classroom.
Real World Connection
In the Real World
When you use Google Maps or any navigation app on your phone, it helps you find the 'far' places and guides you on how to reach them. Even ISRO scientists use this concept to calculate how far their satellites are from Earth.
