Summary of Leyes de Newton (Universo Mecánico 06)

00:00:00 - 00:25:00

Isaac Newton's laws of motion are a simple equation that describe the motion of almost everything in our universe. They are: "F = ma," "the acceleration of a body is constant," and "for every force there is a equal and opposite force." These laws are incredibly powerful, and understanding them well is what makes it possible to understand the universe's mechanical movement.

• 00:00:00 Isaac Newton developed the theory of motion, which is based on the equation "F = ma." In this equation, "F" is the force, "ma" is the mass, and "a" is the acceleration. Newton's three laws of motion are a simple equation that describe the motion of almost everything in our universe. They are: "F = ma," "the acceleration of a body is constant," and "for every force there is a equal and opposite force." These laws are incredibly powerful, and understanding them well is what makes it possible to understand the universe's mechanical movement. At the same time, understanding the enormity of this complication may reside in its seeming simplicity. For example, if we look at the equation "F = ma," we immediately see that it is a vector equation, which means that both the force and the acceleration are vectors. Furthermore, these vectors have specific directions that must be maintained in order for the equation to be correct. Finally, the third law of motion, "G = m(a*a)," is a simple equation that states that the force of gravity is always equal to the mass multiplied by the acceleration (in the direction of gravity). This equation describes the motion of objects in two directions—up and down
• 00:05:00 Newton's three laws of motion explain how objects move and how they are affected by gravity. These laws are: inertia, which states that a body will keep moving in its previous state, even if it is prevented from changing that state by forces; force, which is the only force acting on a moving body; and velocity, which is the speed of an object. These laws can be expressed in differential equations, which are a mathematical way of describing how two or more variables change over time. Newton's second law of motion states that the change in motion is proportional to the force applied. The third law of motion states that objects cannot touch each other without being touched at the same time.
• 00:10:00 The laws of Newton (the mechanical universe 06) are credited to an ancient person who is said to have penetrated and understood them first-hand. despite a considerable difference in their abilities, young David showed the relationship between force and moment of fact. David and Goliat were not as different as legend would have it, after all, this is the model of talent that achieves success through repeated achievement. Newton was not the first person to study the trajectory of an object in flight, but he was the only one to realize that both the trajectory of an object in flight and the motion of planets were governed by the same laws. Galileo Galilei had already described this movement in terms of two independent components decades before Newton. Galileo's extraordinary equation of Isaac Newton (F=ma) is explained in terms of his vision of two independent component motions in flight, something that Aristotelians had not yet understood. For example, when throwing a stone, the Aristotelian view was that there was one force pushing it forward and another pushing it back. Galileo saw that there were two independent forces acting on an object in flight, one pushing it forward and the other pushing it back at the same time. These are the elements of the trajectory of an object in flight.
• 00:15:00 Isaac Newton discovered three fundamental laws of motion, which explained how objects move and helped to shape the field of physics. His theory of universal gravitation, based on his law of gravity, was particularly groundbreaking. Though many other scientists had observed similar curves in projectile trajectories, it was only when Galileo Galilei used a telescope that he actually understood the true parabolic trajectory of a projectile. This insight led to the development of classical mechanics, which would have been incomplete without Newton's principle of inertia.
• 00:20:00 In this video, Newton's laws are summarized in equation form, and explained using a simple analogy of a falling object. In addition, a mathematical problem is solved using these laws. Finally, a demonstration is given of how to shoot an apple off a tree using a laser gun. Without knowing the mass of the apple, or its acceleration, it would be difficult to hit it. However, by using the equation of motion, the mass and acceleration of the apple can be determined.
• 00:25:00 Newton's most important equation, "F=ma," is not about force, but about mass and acceleration. It can be summarized in a single equation: E=mc2. This equation was debated by philosophers for centuries, and it was not until after Newton wrote it that the world became understanding and predictable. Even so, this equation is not without significance; it is used to explain the physics of movement.
