Chapter 81： : Vector has magnitude and direction

It seems that the boy was not affected by Xu Yufei's words.

'S body, which was slightly bent just now, has straightened up, picked up the broom and duster, lifted his foot and walked two steps.

Seeing that the little girl was still looking at him in place.

couldn't help but stop, turned around and asked, "What's wrong."

Jiang Yao's eyebrows curled, and he trot to his side and gave him a thumbs up, "You were so handsome just now. You remember the school rules and disciplines so clearly."

also has more than one hundred entries.

ah ah, one of her girls' hearts is pounding!

Hear the words.

Yan Zhi pursed his lips, and then walked forward.

A cold voice came from the front, with a hint of coolness.

He said, "I used to be curious."

I wondered if it was a display.

But Jiang Yao didn't realize the deep meaning of his words, and nodded as he knew it.

"That's it."

"What's curious about the school rules and disciplines, it always feels useless, and the people who should be restrained are not restrained at all."

Thinking of Xu Yufei, she curled her lips.

Yan Zhi did not respond again.

He puts the **** into the **** bag and wants to sort out the previous rubbish.

Jiang Yao stretched out his hand to help.

was blocked by Yan Zhi, with a clear voice, "Go get your schoolbag."

"Okay."

Jiang Yao had to ran to his seat and took the schoolbag, and flung it on his back.

噔噔噔 ran to the front of Yan Zhi again.

He moves skillfully, packs the sorted garbage, and then tightens it.

Jiang Yao stretched out his hand again to help carry a bag.

The boy hid slightly.

Jiang Yao:...

The little girl pouted dissatisfiedly, looking at him with her watery deer eyes, "I'll just carry a bag."

Yan Zhi's eyes flashed, not looking at her.

He brought up all the **** on his own, his voice was clear and as usual, and there was no doubt about it.

"I come."

then took the lead and walked out of the classroom.

Ms. Jiang had to give up, trot to keep up with him, "Wait for me."

I don’t know if it was intentional or unintentional.

or subconsciously.

Yan Zhi's steps are so small that the little girl can easily follow.

White clouds surge in the blue sky.

Jiangcheng’s mid-May is indeed unbearable, and the temperature remains unchanged at nearly six.

Today's speed is much faster than usual.

After Jiang Yao and Yan Zhi were thrown out, there were still many classmates on campus.

under the tree-lined road.

The little girl stumbled and carried the concept of physics.

"A vector has a magnitude but no direction, a scalar... No right, a vector has a magnitude and a direction, and a scalar has only a magnitude and no direction!"

almost went wrong.

She quietly glanced at the boy next to her.

Seeing Yan Zhi staring ahead, he breathed a sigh of relief.

Next second.

The cool voice of the boy handed it over, "For example."

Classmate Jiang Yao's eyebrows bend.

She can already understand Yan Zhi's concise words that can't be more concise!

"The force of the vector, the moment of force, the linear velocity and angular velocity, the amount of bit movement...Is it impulse?"

She faced the teenager, wringing her eyebrows to think.

Yan Zhi only glanced at her without answering.

Keep walking.

Ms. Jiang made a conclusion two seconds later, "I think it is!"

"Is it right?"

"Um."

Yan Zhi nodded slightly, remembering what he had promised, and added, "That's right."

The little girl smiled more suddenly, and continued, "Then...the scalar has mass, density, temperature, power, and resistance!"

The boy turned his head slightly, looked at her with cold peach blossom eyes, and said lightly, "It's great."

Jiang Yao:! ! !

ah ah ah, my brother praised her, praised her!

Spiral directly in place and ascend to heaven happy!

The beauty in her heart bubbled, and her smile also dyed her eyebrows. She patted her little breast and said proudly, "I think I'm great too!"

While talking, the two had already arrived at the school gate.

Jiang Yao upturned his little schoolbag and raised his eyes.

couldn't help but widen his eyes.
