Introduction Units and Measurement | We know physics is an experimental science. To understand experimental science like physics, we associate our theoretical description of nature with our experimental observation of nature through quantitative measurement. In physics, we deal with numerous…
According to the law of conservation of mass (or the law of conservation of matter), matter is neither created nor destroyed in a chemical reaction or change. It means the total mass of products is equal to the total mass…
Law of conservation of energy is one of the most fundamental concept in all physics. This law states that energy can neither be created nor destroyed, but can only be transformed from one form to another. For instance, when an…
In this chapter, we will understand conservation laws in Physics. During any physical phenomenon governed by different forces, several physical quantities may change with time, but some special physical quantities remain constant with time. Such physical quantities are called “conserved…
We all experience several forces in day-to-day lives. For example, when a moving object hits us, we experience the impact of forces on us. We need a force to push, carry or throw objects, deform or break them. Sir Isaac…
In this chapter, we will understand about different branches of physics. These branches are studied within the scope of physics. We can define the subject physics as: “The branch of science which deals with the study of matter, and energy,…
In this chapter, we will understand about the scope and excitement of physics with the help of examples. First, we will understand the scope of physics. The scope of physics means the extent or range of view. It is truly…
In this chapter, we will learn about what is science, its definition, importance, and various main branches. Imagine you were born about 500 years ago. There was no branch of knowledge at that time. The study of everything was under…
Physics is the most basic discipline in the field of Natural Sciences, which also includes other disciplines, such as chemistry and biology. The word Physics comes from a Greek word “Fusis” which means “nature”. An ancient Greek philosopher Aristotle introduced…
When dealing with solutions, understanding the concentration of a solution is important. The term “concentration” refers to the amount of solute dissolved in one unit of solvent or solution. The concentration of solution is the amount of solute present in…
