Hakikat Ilmu Fisika • Part 1: Hakikat, Ciri-Ciri, Ruang Lingkup, Cabang, dan Manfaat Fisika

Welcome to the Science Window channel. In this video we will discuss the facts of physics, the first part, namely the facts, characteristics, environment, branches, and the benefits of physics. Keep watching this video until the end.

This is the outline or framework of this video part, we will discuss 5 topics. The first is the physical reality, the second is the physical characteristics, the third is the physical environment, the fourth is the branch of physical science, and the fifth is the physical benefits. We start from the physical reality. Science is a science of knowledge that learns natural symptoms through observation, experiment, and analysis.

Physics as one of the branches of science is a science of knowledge that learns matter and energy, as well as the interaction between the two. There are three physical realities. First, physics as a product or a body knowledge. Second, physics as a process or a way of investigating. And lastly, physics as an attitude or a way of thinking.

First, physics as a product is the product of facts, concepts, principles, laws, formulas, theories, and models. Physics as a process must follow the flow of scientific method thinking. And physics as an attitude is a feeling of wanting to know, a feeling of trust, creative, thorough, objective, honest, open, willing to cooperate, and willing to listen to other people's opinions.

These are some physical characteristics. The first, the object studied is a concrete object, namely a real object, real and existent. The second, observation and research are done on purpose through an action in the experiment. The third, the research is done systematically following the scientific method. The fourth, using a logical and consistent way of thinking.

Fifth, the results of the study are objective. Sixth, the physical laws obtained from various trials are general, but with some support. Next, the physical environment. The observation object of physics can be a living being, it can also be a dead thing. While the dead thing can be its activity, it can also be its physical condition. Here I give some examples.

For the activities of living beings, the example is to determine the average speed of someone walking. The object means someone, a living being. What is observed is his activity, the speed when he walks. Next,

The object of the living creature observed by its physical condition is to determine the size of the glasses for the sufferer of Rabun Jauh or Myopi. The object is human, the physical condition is a Ravun Jauh or Myopi. We are asked to determine the size of the glasses.

Next, the activity of the dead object is the speed of the fruit falling from the tree when it grows on the ground due to the influence of gravity. The object means the fruit that falls from the tree, which means the dead object. Then the fruit falls, it's not moving by itself because of the influence of gravity. So the activity is that it falls. Measure how fast it is.

Next, the physical condition of the dead object determines the magnitude of the long addition to a piece of heated iron. Because a piece of heated iron is sure to melt. The condition means that the length increases. Well, the object is the metal, the dead object. The physical condition observed in this case is the length. Okay? Next, the branch of physics. There are many branches of physics, we will discuss some of them.

The first one, Mechanics, studies the movement of objects. The object is a solid macroscopic object. Then there is Fluid Mechanics, which studies the movement of fluids. The object is fluid, namely water and gas. Then there is Quantum Physics, which studies the arrangement of atoms and subatoms, replacing classical mechanics. The object is physical signs in a microscopic environment.

Next is Electronica, this studies radiation, radiation and the impact of electrical charge. The object is a particle or object that is charged with electricity. Next is Electrostatics, this studies silent electricity. The object is a charged particle with a silent charge or does not flow. Next is Electrodynamics, this studies about dynamic electricity. The object is a charged particle with a flowing charge.

Bioelectrodynamics studies the phenomena of electricity and magnets in living beings. Its scientific object is in the network of living beings. Thermodynamics studies thermal properties that affect energy changes, changes in conditions, and changes in the body. Its object is liquid and gas particles that are given by heat.

The next branch of physics is Atom Physics. This studies the structure of atoms, the characteristics of atom accumulators and atom interactions. The object is the atom model. Next, Intimate Physics. This studies the atom core. The object is the atom core. Next, Nuclear Physics. This studies the characteristics, internal structure and use of the atom core. The object is the energy of the atom core.

Next, there is modern physics, which studies matter on an atomic and subatomic scale with high-speed movement. The object is the theory of relativity and particle wave dualism. Next, plasma physics, which studies the ionization gas or plasma. The object is the ionization gas or plasma. Next, wave physics, which studies waves. The object is energy and its properties.

Then there is Optical Physics, this is learning about light, the object is light as an electromagnetic wave. Next there is Medical Physics, this is learning physical application in the field of health, the object is the body of living beings and medical equipment. Next there is Radiation Physics, this is learning the movement of energy that is radiated or absorbed by objects, the object is an electromagnetic wave.

Next is astronomy, this is learning about stars and space objects, the objects are space objects. Next is environmental physics, this is learning about physical events in the environment, the object is the environment, the environment around us on this earth. Next is geophysics, this is learning about the earth with a perspective or physical principles, the object is layers of the earth.

Next is Physics Economy, this is studying physics in the field of economics, the object is the problem of economics. Then there is Computational Physics, this is a combination of physics, computer science, and applied mathematics. The object is the physical equation, so this is usually a formula development using laws or mathematical principles.

Next is acoustic physics, this is learning sound and its application, the object is a sound wave. And the last one here is solid physics, this is learning about the solid structure, the object is solid. Okay, next is the benefits of physics, there are many physical benefits in our daily lives in various fields, here I give some of them.

The first in the field of medicine and health, for example, is Sinaronsen to detect bone fractures, USG to detect baby condition in the womb. The second in the field of agriculture, for example, the discovery of superior seeds from the process of genetic engineering, then there is the creation of agricultural tools that help farmers. The third in the field of transportation,

The physical benefits are the manufacture of Mark Lev trains using superconductors, then there is the manufacture of submarines that apply Archimedes' law. The next field is the industry. This is the use of sonars in the marine industry, then there is the use of waves to detect gas or oil content. Next in the field of communication.

An example of its physical benefits is the use of electromagnetic waves on mobile phones. Then there is the use of optical fiber for the internet network. And lastly, not least in the field of energy, physics plays a role in the use of generators as electricity generators and also the use of solar cells as power generators.
