1、Ok,so we see one billiard ball moving towards another and impact with the second one.
我們看到某臺(tái)球朝另一臺(tái)球運(yùn)動(dòng),并發(fā)生了撞擊。

2、The billiard ball travelled gently across the table.
臺(tái)球慢慢地滾過(guò)臺(tái)面。

3、It is intuitive that if the billiard ball hits the ping-pong ball that it will continue.
需要憑借直覺(jué)的是，臺(tái)球撞擊了乒乓球，而它繼續(xù)運(yùn)動(dòng)。

4、Think about the motion of billiard balls, one billiard ball bashing into another.
想象一下臺(tái)球的運(yùn)動(dòng)，一個(gè)球?qū)α硪粋€(gè)球的撞擊。

5、the motion of the first billiard ball cannot be the real cause of the motion of the second one.
第一個(gè)臺(tái)球的運(yùn)動(dòng),并不是第二個(gè)運(yùn)動(dòng)的真正原因。

6、It just bounces back and the billiard ball almost does nothing.
它反彈回來(lái)，臺(tái)球幾乎沒(méi)有變化。

7、One billiard ball impinged on another.
一個(gè)臺(tái)球撞擊另一個(gè)臺(tái)球。

8、Because when one billiard ball hits another.
因?yàn)?/a>當(dāng)一個(gè)臺(tái)球?qū)α硪粋€(gè)發(fā)生撞擊的時(shí)候。
