1
Para muchos cientรญficos Isaac Newton ha sido el mรกs grande cientรญfico de todos los tiempos.
2
Una de sus mรกs grandes contribuciones fue expresar el comportamiento fรญsico de la naturaleza en forma de leyes.
3
ยฟCรณmo funcionan las leyes de Newton?
4
Tales de Mileto ya habรญa hecho grandes aportaciones a las matemรกticas y a la astronomรญa.
5
astros como el de los objetos aquรญ en la Tierra.
6
Mediante la experimentaciรณn descubriรณ que la velocidad con la que un
7
objeto cae no depende de su peso y tambiรฉn describiรณ cรณmo la Tierra gira alrededor del Sol y no al revรฉs.
8
Luego Johannes Kepler hizo una descripciรณn matemรกtica muy precisa acerca de las รณrbitas de los planetas.
9
El gran mรฉrito de Newton fue tomar los conocimientos de Galileo y Kepler y a partir de sus discusiones con Huygens, Leibniz, Halley y sobre todo Robert Hooke,
10
formular leyes que explican tanto el movimiento de los astros como los movimientos de cualquier otro objeto.
11
And, of course, the mechanics of the machines.
12
All started because Hooke asked to use his math skills to explain the form of the orbit of the asters,
13
for example, the moon around the Earth.
14
Newton told how one day, sitting in the camp and thinking about the problem that Hooke had planned, saw a manzana falling.
15
He asked why the manzana doesn't go to the top or the side?
16
That's the famous "Ley de la Gravitaciรณn Universal" that we'll see a little bit later.
17
But first, let's see the three Leyes of Newton's movement: 1.
18
Newton's law or "Ley de la Inercia" Todo cuerpo persevera en su estado de reposo o movimiento uniforme y rectilรญneo,
19
a no ser que sea obligado a cambiar su estado por fuerzas impresas sobre รฉl.
20
This means that if an object is quiet, it will be quiet, unless a force act on it.
21
Or that if an object is in motion, it will be moving in line rectal, unless a force externe desvies its trajectory.
22
For example, if you push a car, it will be moving in line rectal for a moment, but it will stop because there is a force that pushes it to the lower direction and frees it.
23
And the curve is something similar.
24
For example, if you imprime a force to a ball, but it's amarrated to a cordel, there's a force that's right to the ball,
25
and another that keeps you close your hand.
26
In order to follow a straight line, the ball follows a circular orb.
27
Something similar happens with the orbita of the Luna.
28
The Earth should be able to reach a force of attraction.
29
If the cordel broke, the ball would fall in line straight line.
30
2. Second law of Newton
31
or "Ley fundamental of the dynamic" The change of movement is directly proportional to the motor's force
32
and occurs according to the rectal line along which the force is applied.
33
In simple terms, the amount of power that is imprised to a object, the amount of acceleration will be.
34
Imagine a car that comes in this direction.
35
Trazarรญa este vector.
36
Si un auto con la mitad de su fuerza lo empujara en esta direcciรณn, y suponiendo que el choque fuera elรกstico, su trayectoria se desviarรญa asรญ.
37
Si actuara un tercer auto, esta vez con mรกs fuerza, el vector serรญa este.
38
En resumen, la trayectoria es el resultado de la magnitud de todas las fuerzas que operan en el objeto.
39
Se expresa en la fรณrmula fuerza es igual a masa por aceleraciรณn.
40
3rd Ley de Newton o Principio de la acciรณn y reacciรณn
41
A cada acciรณn siempre se opone una reacciรณn igual pero de sentido contrario.
42
It's to say, If you push something, that something will push you.
43
Imagine that you and a friend that pesa the same thing that you, go on a mountain lo que reduce la fricciรณn.
44
Si imprimes una fuerza en รฉl, no sรณlo รฉl se moverรก, sino tรบ tambiรฉn.
45
La fuerza produce aceleraciones diferentes segรบn las masas de los cuerpos.
46
Si tu amigo es mucho mรกs pesado que tรบ, ยฟadivina quiรฉn se moverรก mรกs?
47
A this motorbike would have been useful to know about Newton's third law.
48
Ouch!
49
It's clear that the laws apply to the objects that touch, touch and push between them.
50
How do they apply to the planets and planets that are separated?
51
Well, Newton decided that the gravity was also a force, but it was also a distance,
52
and its behavior can be described by the law of the universe's gravity.
53
producto de las masas e inversamente proporcional al cuadrado de la distancia que las separa.
54
O sea, mientras mรกs masa tenga un cuerpo, mรกs atraerรก a otros.
55
Y mientras mรกs lejos estรฉn, menos los atraerรกn.
56
La combinaciรณn de estas cuatro leyes ha permitido, desde la construcciรณn de toda clase de mรกquinas,
57
hasta la predicciรณn de la llegada de cometas, e incluso ha permitido construir vehรญculos que han llevado humanos a la Luna.
58
estas leyes y propondrรญa una nueva manera de entender, entre otras cosas, la gravedad.
59
Pero las teorรญas de Einstein no serรญan posibles sin las leyes de Newton, porque, como el mismo Newton decรญa: If I can see far more far,
60
it has been because I've been up to theๅทกir of giants.
61
Curiosamente.

What You'll Learn

This video is a goldmine for building practical English speaking skills. Youโ€™ll practice explaining scientific concepts clearlyโ€”perfect for describing how things work in daily life or academic settings. Youโ€™ll also learn to connect ideas smoothly, like linking historical context (Galileo, Kepler) to modern applications (car movement, planetary orbits). Plus, youโ€™ll get comfortable using conditional phrases (โ€œif you push a car, it will moveโ€) and cause-effect structures (โ€œbecause thereโ€™s a force, the ball changes directionโ€)โ€”key for fluent conversations.

Listen For These Sounds

The speaker uses casual connected speech thatโ€™s common in real-life talks. Notice how โ€œa lot ofโ€ becomes โ€œalotofโ€ (linking the โ€œtโ€ and โ€œoโ€), and โ€œit will beโ€ shortens to โ€œitโ€™ll beโ€ (reduction of โ€œwillโ€). Youโ€™ll also hear softening of โ€œtโ€ sounds, like in โ€œobjectโ€ (pronounced โ€œobjeckโ€) or โ€œvectorโ€ (pronounced โ€œvec-erโ€). These small changes make speech flow naturallyโ€”listen closely to mimic them in your shadow speak practice.

Say It Like a Native

To mirror the speakerโ€™s rhythm, stress key words in each sentence. For example, in โ€œthe change of movement is directly proportional to the force,โ€ emphasize โ€œchange,โ€ โ€œdirectly,โ€ and โ€œforceโ€ to highlight the main idea. The speaker also pauses slightly after introducing each law (โ€œ1. Newtonโ€™s first lawโ€ฆ 2. Second lawโ€ฆโ€)โ€”use these pauses to catch your breath and make your speech sound intentional. Try shadowing the dialogue with a shadowing site to match the pace: start slow, then speed up as you get comfortable. Remember, native speakers donโ€™t rushโ€”they stress important words and connect sounds smoothly. Practice with this video, and youโ€™ll soon sound more natural in English speaking practice. Whether youโ€™re learning English with YouTube or using other tools, focusing on rhythm and stress will take your skills to the next level!
