Physics is the scientific study of matter and energy how they interact with each other. This energy can take the form of motion, light, electricity, radiation and gravity. Physics deals with matter on scales ranging from sub-atomic particles to stars and even entire galaxies. (i.e. the particles that make up the atom and the particles that make up those particles).
How Physics Works?
As an experimental science, physics utilizes the scientific method to formulate and test hypotheses that are based on observation of the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in the language of mathematics, which can then be used to predict other phenomena.
The Role of Physics in Science
In a broader sense, physics can be seen as the most fundamental of the natural sciences. Chemistry, for example, can be viewed as a complex application of physics, as it focuses on the interaction of energy and matter in chemical systems. We also know that biology is, at its heart, an application of chemical properties in living things, which means that it is also, ultimately, ruled by the physical laws.
Why students learn Physics?
Physics is one of the science subjects. Study this subject is going to benefit the students. There are many reasons why we should learn Physics. Some of the benefits are listed here below: Physics is a subject if you wish to pursue higher education in the field of Science, Engineering, Industrial Technology, Materials and Building Science. You need to have good passed in Physics knowledge before you can be accepted into these courses at tertiary levels in university.
Physics arouses our curiosity as to how things work. It challenges our minds to be imaginative and innovative. It contributes greatly and directly to technological advancements throughout history. The application of Physics knowledge in the field of Industrial engineering has resulted in the invention of many wonderful things. For example, when you turn on an electrical switch, the light bulb comes light up. How was the electricity generated in the first place?How a light bulb does works? All these answers are found in the basic application of Physics knowledge.
Physics is the one subject that connected to many other subjects. For example, Chemistry and Biology seemed to be two independent sciences. But at the molecular level, the interactions between atoms and molecules are still best explained through Physics Laws. The medical instruments and equipments that doctors used are all designed by engineers and scientists. These medical instruments worked based on Physics Laws and principles. Physics is a complementary subject to the other sciences. Because physics covers so much area, it is divided into several specific fields of study, such as electronics, quantum physics, astronomy, and BioPhysics.
Today, we are living in the information age. Technology is basic necessity. Technology has its roots in Physics. With good understanding of Physics, you can appreciate the technology better. It helps us to understand the technological advancements.
