Physics is built on a foundation of math and it seeks to explain all phenomena in the universe. It forms the basis for other sciences like chemistry and biology. Physics uses simple yet elegant math to …

Let's think about what physics is and what topics are covered in an introductory physics course.

How can we describe and model motion? How are forces related to changes in an object's motion? How can energy be used to predict the behavior of systems? How are electricity and magnetism related, …

Transverse and longitudinal waves are two types of mechanical waves, which involve the transfer of energy through a medium (e.g. water, air, a solid). Learn about transverse and longitudinal waves …

Bienvenue dans la bibliothèque de physique ! La physique est l'étude de la matière, du mouvement, de l'énergie et de la force. Ici, vous pourrez parcourir des vidéos, des articles et des exercices par …

Welcome to AP®︎/College Physics 1! In AP Physics 1, you'll learn algebra-based classical mechanics. To make sure you’re prepared with the fundamentals, we recommend completing high school …
