PHYSICIAL QUANTITIES :                                                                        A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as a value, which is the algebraic multiplication of a ' Numerical value ' and a ' Unit '. For example, the physical quantity of mass can be quantified as '32.3 kg ', where '32.3' is the numerical value and 'kg' is the Unit. A physical quantity possesses at least two characteristics in common. Dimensions: A physical quantity has a certain number of dimensions, which are the basic units of measurement that are used to quantify it. For example, the dimensions of mass are length, mass, and time. Units: A physical quantity has a certain unit of measurement, which is a standard way of measuring it. For example, the unit of mass is the kilogram. Physical quantities can be classified into two types: Fundamental Quantities:  Fun

Contribution of Muslim Scientists:  Muslim scientists made significant contributions to the field of physics during the Islamic Golden Age. Their work covered a wide range of topics, including optics, astronomy, mechanics, and thermodynamics. One of the most important contributions of Muslim scientists to physics was the development of the scientific method. This method, which relies on experimentation and observation, is still used by scientists today. Muslim scientists were also the first to develop many of the basic concepts of physics, such as force, motion, and gravity.                Here are some of the most notable Muslim scientists who made contributions to physics: 1.Ibn al-Haytham(Alhazen):               He is considered the father of modern optics and his book, "Kitab al-Manazir" (Book of Optics), was influential in the development of optics in Europe during the Renaissance. He also made important contributions to the fields of astronomy, mathematics, and the scie

 INTRODUCTION TO PHYSICS :                                                        Physics is a branch of science that deals with the study of matter, energy, and their interactions. It seeks to explain the fundamental principles that govern the behavior of the physical universe, from the smallest subatomic particles to the largest structures in the cosmos.                The study of physics is based on observations, measurements, and mathematical models that allow scientists to make predictions about the behavior of physical systems. It covers a wide range of topics, including mechanics, electromagnetism, thermodynamics, quantum mechanics, and relativity.               The study of physics has contributed greatly to the development of technology and the understanding of the natural world. It is essential to fields such as engineering, chemistry, and astronomy, and has led to numerous technological advancements such as electricity, telecommunications, and computers. BRANCHES OF PHYSICS
