Abstract

Introduction to the Physics Course for First-Year Biological Science Students Physics is a fundamental science that provides the basis for understanding the natural world by exploring the principles governing matter, energy, and their interactions. This course is designed for first-year students in the Common Core of Biological Sciences, following the official curriculum set by the Ministry of Education. It aims to equip students with essential physics concepts relevant to their field of study, emphasizing problem- solving skills and practical applications. The course is structured into four comprehensive chapters, each addressing a key area of physics: Chapter 1: Mathematical Remender in Physics This chapter introduces essential mathematical tools for analyzing physical problems and consists of three main sections: - Dimensional Analysis: A powerful method for verifying equations, ensuring the consistency of physical expressions, and understanding the relationships between different physical quantities. - Vector Analysis: A crucial topic for understanding physical quantities that have both magnitude and direction, which is essential in various branches of physics, including the different of products (scalare and vectorial prodects). - Errors and Incertainty: This section explores the conditions under which physical systems reach a state of balance, laying the foundation for future studies in mechanics and fluid dynamics. Chapter 2: Geometrical Optics Light plays a crucial role in both physics and biological sciences. This chapter covers fundamental principles of geometrical optics, including: - Descartes’ Laws of Reflection and Refraction: These laws govern how light interacts with different surfaces and materials, forming the basis for optical studies. - Lenses and Mirrors: Understanding image formation through convex and concave lenses and mirrors, which is essential in vision science, microscopy, and optical instruments. - Prisms: Exploration of light dispersion and color separation using prisms, which has applications in spectroscopy and optical analysis. Chapter 3: Fluid Mechanics Fluids are a vital component of biological systems, from blood circulation to respiratory processes. This chapter covers: - Fluid Statics: Concepts such as pressure, buoyancy, and Pascal’s and Archimedes’ principles. - Fluid Dynamics: Key topics include Bernoulli’s equation, viscosity, and laminar versus turbulent flow. These concepts are crucial for understanding biological fluid transport mechanisms. Chapter 4: Concept of Crystallography This chapter introduces crystallography, an essential field in materials science, chemistry, and biology. It provides an overview of: - Crystal Structures and Properties: Understanding how atomic arrangements influence material properties. - X-ray Diffraction and Applications: Exploring how crystallographic techniques are used to study molecular structures, including DNA and protein structures. To enhance understanding, this course includes detailed lessons, worked-out examples, problem sets, and laboratory exercises. These components help students apply theoretical knowledge to practical scenarios, fostering scientific reasoning and analytical skills. By the end of this course, students will have a solid foundation in physics, preparing them for advanced studies in biological sciences and related fields."
