Hello friends!
2
Today we will learn about the types of force.
3
You are playing here in the park.
4
Could you throw the ball straight up?
5
See?
6
It came back!
7
The ball went up because you applied a force to it.
8
And it came back because of the force applied by Earth.
9
Force is a push or a pull of an object that causes the object to speed up, slow down, or stay in one place.
10
You know, there are two types of forces, contact forces and non-contact forces.
11
Let's learn about these one by one.
12
Contact forces.
13
Contact forces are forces in which two or more objects or bodies touch or contact each other directly.
14
An example of contact force is sandpaper rubbing on a piece of wood.
15
Here, the two objects touch each other.
16
Let's see the types of contact forces.
17
Frictional force.
18
It is the force generated by two surfaces that contact and slide against each other.
19
Here, the force is opposing the movement between you and the surface, which is sliding against each other.
20
Normal force.
21
Look at this cute cat!
22
It experiences a normal force from the ground that balances its weight, allowing it to remain stationary.
23
The normal force is defined as the force that a surface employs on any other body.
24
The force exerted by a table on a book resting on it is also an example of normal force.
25
Tension force.
26
It is defined as the force transmitted through a rope, string, or wire when pulled by forces acting from opposite sides.
27
Applied force.
28
A boy pulling a suitcase on its wheels applies a force on the handle of the suitcase.
29
When an object attracts or repels one or more other objects, it is said to be applying some force.
30
Air Resistance Force This is a type of force that acts in the opposite direction to an object moving through the air.
31
Airplanes, helicopters, and birds are all examples of objects that regularly encounter air resistance.
32
Spring Force You are playing with this spring toy.
33
The spring is stretching and compressing, which results in a force that causes the movement.
34
If the spring is stretched, spring force is attractive.
35
If it is compressed, spring force is repulsive.
36
You have seen the types of contact forces.
37
Now we will see the non-contact forces.
38
See a mango is falling from the tree.
39
What is an example of a non-contact force?
40
A non-contact force is a type of force that acts on the object without any physical contact with it.
41
You have started eating this juicy mango.
42
Let's see different types of non-contact forces.
43
Gravitational force.
44
When you were washing the mango, the water was coming downwards.
45
It was due to the gravitational force, which is the force of attraction between all masses in the universe.
46
Electrical force.
47
The repulsive or attractive interaction between any two charged bodies is called electrical force.
48
For example, the charge in a bulb and electrical circuits.
49
Magnetic force A magnet is a rock or a piece of metal that can pull certain kinds of metal toward itself.
50
The force of magnets is called magnetism.
51
You have prepared a chart.
52
Could you show it to your friends?
53
Types of Forces Contact and non-contact You can use it for your assignments
54
Now you know a lot about types of forces Stay tuned for more videos Bye-bye

Por que praticar fala com esse vídeo?
Esse vídeo sobre tipos de força é perfeito para quem quer aprender inglês com vídeos de forma divertida e eficaz! A linguagem é clara, adaptada para crianças (mas ideal para iniciantes de qualquer idade) e repleta de contextos reais, como brincar no parque ou observar um gato. Isso torna o shadow speech (imitar a fala) mais fácil, pois as situações são familiares. Ao praticar com ele, você melhora a pronúncia, a fluência e aprende vocabulário técnico de ciências de forma natural. É como ter aulas de inglês e física ao mesmo tempo! E o melhor: o ritmo calmado do narrador permite que você siga passo a passo, ideal para quem usa shadowspeak como método de aprendizado.
Gramática e expressões no contexto
Vamos analisar algumas estruturas chave do vídeo que vão te ajudar a falar inglês com mais confiança:
- "Force is a push or a pull of an object that causes...": A estrutura "is a [noun] or a [noun] that [verbo]" é essencial para definir conceitos. Use-a para explicar coisas no dia a dia, como "A casa é um lugar ou um espaço que protege de chuva".
- "It came back because of the force applied by Earth": "Because of" (por causa de) é uma expressão usada para explicar causas. Diferente de "because" (que precisa de uma frase), "because of" usa substantivos. Exemplo: "Fiquei atrasado because of o trânsito".
- "If the spring is stretched, spring force is attractive": A condicional "if" (se) no presente é usada para situações reais. Pratique frases como "If I study, I pass the test" (Se eu estudo, eu passo no teste).
Traps comuns de pronúncia
Algumas palavras no vídeo podem ser difíceis de pronunciar, mas com prática, você consegue! Veja os principais:
- "Frictional force": A palavra "frictional" tem o som "fríc-shunal" (não "frik-sional"). Preste atenção no "sh" no meio. Use um shadowing site para ouvir repetidamente e imitar.
- "Gravitational": A pronúncia correta é "gra-vi-ta-shunal" (não "gra-vi-ta-cional"). O "t" se transforma em "sh" antes de "i".
- "Repulsive": Diga "ri-pul-siv" (não "re-pul-siv"). O "e" no início é curto, como em "red".
Lembre: o shadow speech é a melhor forma de superar essas dificuldades. Repita as frases do vídeo várias vezes, tentando igualar o tom e o ritmo do narrador. Você vai ver que, com o tempo, essas palavras vão ficar naturais!
Gramática neste vídeo
As estruturas que o falante mais usa, com as palavras exatas do vídeo:
| Estrutura | No vídeo |
|---|---|
| Voz passiva be + particípio passado — o foco está no que acontece, não em quem faz | is defined · is said · is stretched |
| Present perfect have/has + particípio passado — uma ação passada que ainda importa agora | have seen · have started · have prepared |
| Orações relativas who / which + oração — informação extra sobre uma pessoa ou coisa | surface, which is · force, which is |
| Present continuous am/is/are + -ing — algo que está acontecendo agora ou nestes dias | are playing · is opposing · is stretching |
O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
