Ye Xiaoyu and Sa Manman walked into the teacher's office with anxiety.

I saw that Lin Mo was actually here.

"Why are you here?" Ye Xiaoyu was a little surprised.

Lin Mo said: "Come and ask the teacher questions. ”

Ye Xiaoyu sighed.

Then came the question time.

Ye Xiaoyu came first.

"The definition of average velocity."

“v=s/t”

"Acceleration Formula."

“a=（Vt-Vo）/t”

"Major physical quantities and units."

"The initial velocity v0, the acceleration a, the end velocity vt, the time t.... Hm..."Ye Xiaoyu broke his fingers and said little by little, finally stuck, "Time, displacement t, m m." ”

"What is the movement of free fall."

Ye Xiaoyu was shocked. This is the knowledge she memorized the day before yesterday, and she has forgotten it.

The sa man next to her wanted to prompt, but she stood next to Ye Xiaoyu and was not good at prompting.

Lin Mo quietly walked behind Li Jian and reminded Ye Xiaoyu with his mouth.

"Uh.... The initial velocity is zero.... Linear motion. ”

Lin Mo and Li Jian supported the forehead.

Li Jian felt that something was wrong, turned his head and found Lin Mo behind, frowned and said, "What are you doing behind me, you can't prompt it." ”

Lin Mo explained: "I don't have it, I just want to see how the teacher writes, so that it looks better." ”

Li Jian didn't believe it, and said to Lin Mo: "You stand next to you first, and I'll teach you later." ”

Lin Mo had no choice but to respond, and gave Ye Xiaoyu a look of "I can't help".

Without Lin Mo's strong backing.

Ye Xiaoyu was a little desperate, and he stumbled and didn't say an answer.

In the end, Li Jian gave an ultimatum mercilessly: "Copy the free fall movement 10 times, let Li Jun copy it 30 times." ”

Although Ye Xiaoyu was a little disappointed, he replied very happily: "Okay." ”

He looked like a eunuch.

Then it's sprinkled full.

Despite the help of Ye Xiaoyu's gestures, there were still two wrong.

So Li Jian punished him for copying 20 times. Li Jun copied it 30 times.

The two returned to the classroom in a wonderful mood.

Just stepped through the classroom door. Li Jun raised his head as if he had a sense and asked, "How is it?" ”

Ye Xiaoyu smiled ill-willedly: "Don't worry, it's not a lot, just 90 times without panic." ”

Li Jun despaired: "Wait, wait, is it you who contributed 90 times, or two people who contributed 90 times together." Personally, I would like the latter. ”

Ye Xiaoyu hesitated for a moment and said, "Congratulations, it's the latter." ”

Li Jun breathed a sigh of relief, and then asked, "How many did you contribute, and how many did he contribute?" ”

Ye Xiaoyu told him where he wanted to copy. 90 times is still a bit much.

Li Jun was helpless, silently picked up the pen and copied it hard. Schadenfreude sounded all around.

Li Jun silently reminded himself in his heart, next time he must kill these two people who will affect me. They were definitely sent from heaven to target me.

Later, in Li Jun's focus on the students of the horizontal and vertical rows:.

"Ye Xiaoyu, how to ask for free fall, will you do it? Did you write the question I asked you to do? ‘’

"Sprinkle it full! What kind of novel do you read, do you understand uniform linear motion? ”

Ye Xiaoyu put down the snacks in his hand very cowardly: "Ah.... I—" The eyes of the crowd were 'eyeing each other'.

Ye Xiaoyu immediately put down the snacks in his hand, and looked 'I'm serious, I'm working hard': "I'll do the question...."

Samanman just wanted to speak.

Everyone: "Huh? ”

Sprinkle full: I carry ...... I can't carry it yet.

Under the 'surveillance' of everyone, Ye Xiaoyu and Sa Manman's results finally made such a little progress.
