Physics 1 course by Math and Science

About this course

Understanding physics is easier when the ideas connect and the math stops feeling like a barrier. This free online Physics 1 course is designed to help you build a solid foundation from the ground up, so you can read problems with confidence, choose the right approach, and explain results clearly. Whether you are reinforcing school learning, preparing for exams, or returning to the subject after a break, you will develop the habits and intuition that make physics feel logical rather than intimidating.

You will start with the big picture of what physics studies, then move into core concepts such as force and motion, the basic relationship between heat and work in thermodynamics, and key ideas in electricity and magnetism. Instead of treating these topics as isolated facts, the course helps you see patterns: how laws describe nature, why units matter, and how to interpret what a situation is asking before plugging in numbers.

Because success in physics depends on clear math and measurement skills, you will also strengthen the tools that support every solution. You will review essential algebra, trigonometry, and scientific notation, then apply them to physics units, the metric system, and practical unit conversions. This makes it easier to avoid common errors and to communicate answers in a form that is scientifically meaningful.

A major focus is learning to think in vectors. You will learn the difference between scalars and vectors, how to add and subtract vectors graphically, how scalar multiplication changes magnitude and direction, and how to break vectors into x and y components. These skills are fundamental for analyzing displacement, velocity, and many real-world motion problems. Practice questions throughout the course help you check understanding, correct misconceptions early, and build problem-solving speed without sacrificing accuracy.

By the end, you will be better equipped to tackle introductory physics with a structured method, stronger math fluency, and clearer physical intuition—skills that transfer directly to further science study and many technical pathways.
