Physics comes from the Greek which means "nature". Physics is a science that studies the properties and symptoms of objects in nature. These symptoms are initially what our senses experience, for example, sight finds optics or light, hearing finds lessons about sound, and the sense of touch can feel heat.
Why do we need to study Physics? Physics is a fundamental science, because it deals with the behavior and structure of objects, especially inanimate objects. According to history, physics is the oldest field of science, because it begins with observations of the motion of the celestial bodies, how their trajectories, periods, ages, and so on. This field of science began centuries ago, and developed during the time of Galileo and Newton. Galileo formulated the laws of falling objects, while Newton studied motion in general, including the motion of the planets in the solar system.

In modern times like today, physics is very supportive of the development of technology, industry, communication, including engineering, chemistry, biology, medicine, and others. Physics can answer questions about interesting phenomena. Why does the earth revolve around the sun? How can air hold a heavy airplane? Why does the sky appear blue? How can TV broadcasts/shows reach faraway places? Why are electrical properties so important in communication and industrial systems? How can guided missiles be aimed at targets that are very far away, even between continents? And finally, how did the plane land on the moon? These are all studied in various fields of physics.
The field of physics is broadly divided into two groups, namely classical physics and modern physics. Classical physics is based on the symptoms that are caught by the senses. Classical physics includes mechanics, electricity, magnetism, heat, sound, optics, and waves which are the boundary between classical physics and modern physics. Modern physics developed from the 20th century, since the discovery of Einstein's theory of relativity and radioactivity by the Curie family.
The Relationship of Physics with Other Sciences
The purpose of studying physics is so that we can know the basic parts of objects and understand the interactions between objects, and be able to explain natural phenomena that occur. Although physics is divided into several fields, the laws of physics apply universally. A review of a phenomenon from a particular field of physics will get the same result when viewed from another field of physics. In addition, the basic concepts of physics not only support the development of physics itself, but also the development of other sciences and technology. Physics supports both pure and applied research. Geologists in their research use gravimetric, acoustic, electrical, and mechanical methods. Modern equipment in hospitals applies physics. Astronomers need spectrograph optics and radio engineering. Likewise meteorologists (weather science), oceanologists (marine sciences), and seismologists need physics.
Physics in the Field of Measurement
Physics was born and developed from the results of experiments and observations. Experiments (experiments) and observations (observations) require measurement with the help of measuring instruments, so that quantitative data/observations are obtained. For example, the results of measurements in an experiment obtained a measured length of 4 meters, a volume of 10 cm3 of water at a temperature of 15 °C. In physics, length, volume and temperature are things that can be measured. Something that can be measured is called a quantity. Quantity has two main components, namely value and unit. In physics, keep in mind that not all physical quantities have units, for example refractive index and relative density.
Physics is very necessary in the structural engineering to make calculations and simulations based on technical engineering, studying physics besides being able to provide an understanding of nature can also require humans to have logical thinking.
