1
In science we often hear the word force.
2
But what is a force and what happens when forces are applied to the objects around us?
3
Forces are what make things move.
4
You can think of a force as a push or a pull.
5
A push is when you apply force to move something away from you.
6
you A pool? is when you apply force to bring something closer to you.
7
you Every time you push or pull something, you're using a force.
8
Here are some examples to help you understand.
9
When you throw a ball, you are pushing it away from you.
10
When you pull on a fishing rod You are pulling the rod and line
11
and hopefully a fish, towards you you you Another example is opening a door.
12
When you push a door open, you are using a force to move it.
13
And when you play tug of war, You and your team are pulling on the rope to try and move the other team.
14
you Forces can be different in size or strength, which is called magnitude.
15
and they can also be different in direction.
16
Forces of different magnitudes and directions affect the movement of objects in different ways.
17
The size of the force applied to an object affects how fast it moves and how far it goes.
18
For example, if you kick a ball gently, you're using a small force.
19
The ball moves slowly and moves a short distance But if you kick it as hard as you can,
20
you're using a large force and the ball moves faster and further.
21
you Thank you.
22
The direction of a force is also important.
23
you If you push a toy car forward, it will move forward.
24
If you throw a ball straight up, it will go up into the air.
25
you The direction in which you apply the force determines the direction in which the object will move.
26
you you For example, if you kick a ball to the side,
27
it will go in that direction rather than straight So,
28
generally, an object will move in the same direction of the force applied to it.
29
Forces are all around us and they make things move in different ways.
30
By understanding the magnitude and direction of forces, we can better understand how things move and why they move the way they do.
31
How do you think the mass or weight of an object affects how it moves when forces are applied to it?
32

33
Thanks for learning and I'll see you again soon.
34
you Music.

この動画の文法

話し手がよく使っている文型を、動画の実際の表現とともに紹介します。

文型動画での表現
受動態 be + 過去分詞 — 誰がするかより、何が起きるかに焦点を当てるare applied · is called
現在進行形 am/is/are + -ing — 今まさに、または最近起きていることyou're using · are pushing · are pulling
「will」の未来表現 will + 動詞 — その場の決定、約束、予測will move · will go · I'll see

注意したい発音

話し手はyou're, don't, I'llなど、短縮形や弱形を5回使っています。聞こえたとおりの短い形で発音しましょう。

  • 「th」の音: throw /θɹoʊ/, strength /ˈstɹɛŋθ/
  • 「sh」と「zh」の音: direction /dɪˈɹɛk.ʃən/, push /pʊʃ/, fish /ˈfɪʃ/

日本語話者が苦手な音：

  • /f/ — 「フ」ではなく、上の歯と下唇で出す: affect /əˈfɛkt/, hopefully /ˈhoʊp.fə.li/, fish /ˈfɪʃ/
  • 子音の連続 — 間に母音を入れない: gently /ˈd͡ʒɛntli/, subscribe /səbˈskɹaɪb/, object /ˈɑb.d͡ʒɛkt/, affect /əˈfɛkt/, slowly /ˈsloʊli/

  2. 通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
  3. 自分の声を録音して元の音声と比べます。magnitude, gently, ropeなどの単語に特に注意しましょう。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
