1
So, physics.
2
Ah, right.
3
Physics.
4
Physics, physics, physics.
5
You get into all this?
6
We have been talking about doing Crash Course Physics for a long, long, long, long time.
7
You've wanted it, we've wanted to do it, and now, thanks to our friends at PBS Digital Studios, we're doing it.
8
There's just one thing.
9
I'm hosting Crash Course Philosophy, but I do know someone super qualified for the job.
10
Hi.
11
Hi.
12
This is our host for Crash Course Physics, me.
13
I'm gonna go have a corn dog and host philosophy.
14
Take it away, Shinny.
15
I'm Dr. Shinny Somara, a mechanical engineer and fluid dynamicist by qualification.
16
For the last few years, I've been hosting science and tech shows on TV like Techno, Tomorrow's Food, and The Health Show.
17
Want to know more about me?
18
There are links in the doobly-doo.
19
So, let's talk physics!
20
I love physics, and chances are you do too, even if you don't know it yet.
21
So I'm really excited to host this series of Crash Course.
22
In this series, we'll be covering AP Physics 1 and 2 mostly, but we'll also have a little time for other things along the way.
23
Everything you do, build or say, will be governed by physics, so wouldn't it be nice to read the rulebook?
24
A rulebook that will help you through life.
25
Physics is elegant.
26
It's also practical and fun.
27
Understanding time, position, velocity and acceleration and how they all work together can help you understand your place in the universe.
28
Literally.
29
And I'm sure you've heard of Newton's laws, like his first law.
30
An object in motion will remain in motion.
31
an object at rest will remain at rest, unless acted upon by a force.
32
But what does that mean?
33
And what does it have to do with acceleration?
34
And what are vectors?
35
Scalars?
36
And what does this mean?
37
Kinetic friction and static friction?
38
What's the difference?
39
We'll explain all of that, but what's more special is getting to figure out why understanding these things is so valuable.
40
Understanding how the world, the universe, works gives us a richer and more immersive experience in life.
41
it gives us the opportunity to see the beauty in nature in vast and unexpected ways.
42
Now, a lot of people think physics is hard, but it's easy.
43
Well, as easy as we can make it.
44
So join me, Dr. Shinise O'Mara, this year on Crash Course Physics, which was produced in association with our good friends at PBS Digital Studios.

  • أصوات “sh” و“zh”: acceleration /əkˌsɛl.əˈɹeɪ.ʃən/, friction /ˈfɹɪkʃən/, qualification /ˌkwɑlɪfɪˈkeɪʃən/
  • الكلمات الطويلة — انتبه لموضع النبر: acceleration /əkˌsɛl.əˈɹeɪ.ʃən/, mechanical /məˈkænəkəl/, unexpected /ʌnɪkˈspɛktɪd/, velocity /vəˈlɑsəti/, qualification /ˌkwɑlɪfɪˈkeɪʃən/

كيف تتدرب بهذا الفيديو

  1. استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
  2. ابدأ بسرعة 0.75×، وردّد جملة جملة، ثم عُد إلى السرعة العادية عندما يصبح الأمر سهلًا.
  3. سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل physics, acceleration, friction.

القواعد في هذا الفيديو

أكثر التراكيب التي يستخدمها المتحدث، مع العبارات نفسها من الفيديو:

التركيبفي الفيديو
المضارع التام المستمر have/has been + -ing — حدث بدأ سابقًا وما زال مستمرًاhave been talking · I've been hosting
المضارع التام have/has + اسم المفعول — حدث ماضٍ ما زال له أثر الآنYou've wanted · you've heard
المبني للمجهول be + اسم المفعول — التركيز على ما يحدث لا على من يفعلهwill be governed · was produced

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
