    Introduction

    The prime objective of this course is to understand the universe, our nature, particle, object, motion, and states of matter, Context of everyday objects. Physics it’s one of the oldest subjects, which deals with object/matter and finds out the relationship with energy. It involves the study of physical and natural phenomena around us. Examples of these phenomena are the formation of the rainbow, the occurrence of the eclipse, the fall of things from up to down, the cause of sunset and sunrise, the formation of shadow, and many more. On our Course topics, we shall discuss four basic elementary parts of Physics, such as:

    i) Mechanics: This branch deals with static and dynamic objects, rigid bodies, circular motions, etc. Under this branch, we look into details of the aspects of linear, circular, and oscillatory motions as well as the motion of fluids, also we will get ideas about frictional force and relation with the objects. Also, we get ideas about projectile motion and so on.

    ii) Waves: it deals with the study of the propagation of energy through space.

    iii) Optics: Theory of Light: It deals with reflection, refraction, interference, and much more wonderful phenomenon of light, it will give generalized ideas about color, the function of light, and its uses.

    iv) Electricity & Magnetism: Basic Concepts of Charges and Electricity: What is Charge? Explanation of Charge, Electric Potential Energy, 
    and Electricity: What is Charge? Explanation of Charge, Electric Potential Energy, Current, Current Density, Resistance, Resistance in Series and Parallel Combination, Resistivity and Conductivity,  Magnetic field, Magnetic field Strength,  Biot-SavartLaw, Application of Biot-Savart’s law, Ampere’s Law, Magnetic Properties of Material, Electromagnetic Waves, Concepts of (Motor, Generator, Transformer, Transistor), etc.  Resistance, Resistance in Series and Parallel Combination, Resistivity and Conductivity,  Magnetic field, Magnetic field Strength,  Biot-SavartLaw, Application of Biot-Savart’s law, Ampere’s Law, Magnetic Properties of Material, Electromagnetic Waves, Concepts of (Motor, Generator, Transformer, Transistor), etc.
