Introduction
When an object is either pushed or a pulled is known as a force. Motion, generated in an object, is because of an action of a force. The applied force makes the table move in a given direction. The strength of a force is commonly expressed by the magnitude. Force also has direction; likewise, if…

Nobel Prize In Physics
Introduction The Nobel Prize in Physics is the most prestigious award given yearly by the Royal Swedish Academy of Sciences. The Noble prize is given to those physicists who conferred the most outstanding contributions for mankind (in physics). Wilhelm Röntgen, a German/Dutch physicist, was the first person who had received the first Nobel Prize in…

Development of Physics
During the ancient period, the development of physics took place with the development of astronomy. However, during the medieval period, a notable work of the Arab writer and scientist Ibn Al-Haitham revolutionized the concept of physics. Ibn Al-Haitham had written a book in seven volumes namely “Kitāb al-Manāẓir “also known as “The Book of Optics.”…

Introduction
Physics is one of the most significant disciplines of natural science, which describe the nature and properties of matters. The term ‘physics’ is derived from the Ancient Greek word i.e. ‘phusikḗ’ meaning ‘knowledge of nature’. Definition Physics is the branch of natural science that studies the nature and properties of matter and energy. The significant subject matter of…

Unit of Magnetic Field
When we talk about the magnetic field, different units are used to measure it. Basically, there are two systems of units based on the metric system used: the SI unit and CGS units. Thus, we will look at the unit of magnetic field below. SI Unit of Magnetic Field Generally, the magnetic field can be defined in…

Unit of Current
Introduction: We have heard a lot about electric currents in our classrooms as well as at home. While the topic is highly relatable, in more scientific terms an electric current is basically a flow of current or charge in electric circuits. Sometimes both ions and electrons carry the charge simultaneously. Electric current or charge is measured by an…
