What is it?

Slow means taking a long time to do something or moving at a low speed. When something is slow, it covers less distance in a certain amount of time compared to something fast.

Simple Example

Quick Example

Imagine your friend walks to school, and you ride your bicycle. If your friend takes 20 minutes and you take 5 minutes to reach the same school, your friend is walking slow compared to your bicycle ride.

Worked Example

Step-by-Step

Let's compare two auto-rickshaws.

Step 1: Auto A travels 10 kilometers in 30 minutes.

---

Step 2: Auto B travels 10 kilometers in 20 minutes.

---

Step 3: To find out which is slower, we compare the time taken for the same distance.

---

Step 4: Auto A took 30 minutes, and Auto B took 20 minutes to cover 10 km.

---

Step 5: Since Auto A took more time (30 minutes > 20 minutes) to cover the same distance, Auto A is slower.

---

Answer: Auto A is slower than Auto B.

Why It Matters

Understanding 'slow' is key in physics to measure speed and velocity. In computing, it helps us understand why some apps load faster than others. AI uses this to optimize processes, like making a robot move efficiently. This concept is used by engineers designing faster cars or by doctors analyzing heart rates.

Common Mistakes

MISTAKE: Thinking 'slow' always means 'bad'. | CORRECTION: Slow isn't always bad. Sometimes, being slow and careful is important, like when a surgeon operates or when you're solving a tricky math problem.

MISTAKE: Confusing 'slow' with 'stationary' (not moving). | CORRECTION: Slow means moving, but at a low speed. Stationary means not moving at all.

MISTAKE: Not considering the distance covered when comparing speeds. | CORRECTION: To accurately compare if something is slow, you must compare the time taken for the same distance, or the distance covered in the same amount of time.

Practice Questions

Try It Yourself

QUESTION: A snail moves 1 cm in 10 seconds. A tortoise moves 10 cm in 10 seconds. Which is slower? | ANSWER: The snail is slower.

QUESTION: Your internet download speed is 5 MB per second. Your friend's download speed is 2 MB per second. Whose internet is slower? Explain why. | ANSWER: Your friend's internet is slower because it downloads less data (2 MB) in the same amount of time (1 second).

QUESTION: A train travels 120 km in 2 hours. A car travels 90 km in 1 hour. Which vehicle is slower? Show your working. | ANSWER: Train speed = 120 km / 2 hours = 60 km/hour. Car speed = 90 km / 1 hour = 90 km/hour. Since 60 km/hour is less than 90 km/hour, the train is slower.

MCQ

Quick Quiz

Which of these describes something moving slowly?

A cricket ball hit for a six

A rocket launching into space

A person walking leisurely in a park

A bullet leaving a gun

The Correct Answer Is:

A person walking leisurely moves at a low speed compared to a cricket ball, rocket, or bullet, which are all examples of fast motion.

Real World Connection

In the Real World

Think about traffic jams in Mumbai or Bengaluru. When vehicles move very slowly, it means they cover very little distance in a lot of time. This 'slow' movement affects how quickly delivery apps like Swiggy or Zomato can get your food to you, or how long your daily commute takes.

Key Vocabulary

Key Terms

SPEED: How fast something is moving | DISTANCE: How far something travels | TIME: The duration taken for an event | VELOCITY: Speed in a particular direction
