In a village lived a clever girl named Aditi and her younger brother, Aryan. They saw their grandmother struggling to pull a heavy bucket of water from the deep well near their home.

 Daadi  is pulling a heavy bucket from the well. Her hands grip the rope tightly, and her face shows effort. Aditi and Aryan stand nearby, watching with curiosity and concern. 

“Daadi, why is it so hard to pull the bucket up?” Aryan asked, worried.
“Yes,” Daadi explained. “This effort is due to the force I am applying to the bucket by pulling it upward. A force is a push or pull. Right now, I’m pulling the bucket up, but gravity is pulling it down, which makes it feel so heavy.”

“Gravity? What’s that?” Aryan asked, scratching his head.

Aryan, there has to be a way to help Daadi!”

Aryan nodded. “Let’s ask Chacha! He’s always fixing things at his workshop.”

The two rushed to their uncle’s workshop, where tools, ropes, and wooden planks were scattered everywhere.

“Chacha, can you help us make something to make Daadi’s work easier?” Aditi asked eagerly.

Chacha smiled. Of course! We can make a pulley. It’s a simple machine that makes lifting heavy things much easier.

A pulley? What’s that? Aryan asked.

Chacha said, “A pulley is a wheel with a groove around it. When you pass a rope through the groove, it changes the direction of force. Instead of pulling straight up, you pull down, and it feels lighter”

“Can we make one?” Aditi asked excitedly.

“Sure! Let’s get some materials,” Chacha said. They found an old bicycle wheel, a rope, and a wooden frame.

First, they attached the wheel to the wooden frame using nails. Then, they threaded the rope through the groove in the wheel and tied one end to an empty bucket.

Aditi pulled the rope. the bucket lifted smoothly.

“That’s the power of the pulley, It doesn’t make the bucket weigh less, but it helps you use less force to lift it.”

The next morning, Daadi tried the pulley and was amazed. “Wah! This is wonderful! It’s so easy now!”

In a peaceful village, Aditi and her little brother Aryan watched their Daadi pulling a heavy bucket from the well. Daadi's hands gripped the rope tightly, and her face showed effort. Aryan, worried, asked, "Daadi, why is it so hard to pull the bucket up?" Daadi explained, "This effort is due to the force I am applying to the bucket by pulling it upward. Gravity is pulling it down, which makes it feel so heavy."

Aryan scratched his head and asked, "Gravity? What's that?" Aditi, thinking hard, said, "Aryan, there has to be a way to help Daadi!" Aryan nodded and suggested, "Let's ask Chacha! He's always fixing things at his workshop." The two siblings rushed to their uncle's workshop, where tools, ropes, and wooden planks were scattered everywhere. "Chacha, can you help us make something to make Daadi's work easier?" Aditi asked eagerly.

A New Idea

Building the Pulley
