SSC English Version Physics Note Chapter 4: Work Power and Energy

SSC English Version Physics Note Chapter 4: Work Power and Energy. By work, we mean to do something in our everyday life. But in physics, it refers to a specific concept. At the beginning of this chapter, we will present this concept. The most important topic in science is energy. From our experience, we see that the world becomes inactive without energy. We get energy in different forms. Such as kinetic energy for motion, potential energy for an object in a higher position from the ground, the energy of spring at contract condition or expanding condition, heat energy of the hot body, electrical energy of charged body etc. The energy is transforming from one form to another gradually although the total energy of the universe remains unchanged and constant. In this chapter, we will discuss the transformation of energy and the law of conservation of energy, one of the important laws of science.

The physics is one of the oldest academic disciplines, perhaps the oldest through the inclusion of astronomy. In the last two millennia, physics was a part of natural philosophy, chemistry, certain branches of mathematics and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique in its own right research programs. Physics intersects with many interdisciplinary areas of research, such as Biophysics and quantum chemistry, and physics limits are not rigidly defined. New ideas in physics often explain the fundamentals of other sciences mechanisms, to open new avenues of research in areas such as mathematics and philosophy.

Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. Over the last two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the scientific revolution in the 17th century, these natural sciences emerged as unique research endeavors in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in academic disciplines such as mathematics and philosophy.

teachingbd24.com is such a website where you will get all kinds of necessary information regarding educational notes, suggestions and question patterns of schools, colleges, and madrasas. Particularly, you will get here special notes of physics that will be immensely useful to both students and teachers. The builder of the website is Mr. Md.
