Course Introduction

Introductory Physics provides students with a foundational understanding of the laws governing the physical world, covering key topics such as mechanics, energy, waves, and thermodynamics. Emphasizing problem-solving and conceptual reasoning, the course integrates fundamental principles like Newton's laws of motion, conservation of energy and momentum, and the basics of fluids and heat. Through lectures, laboratory experiments, and real-world applications, students develop critical scientific skills and an appreciation for the role physics plays in technology, the environment, and everyday life. This course is ideal for those beginning their studies in science, engineering, or any field that benefits from a solid grounding in physical principles.
