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.

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 …

Let's solve some problems to better understand the behavior of forces that act on objects, and their effects on motion. In the process, we will clear some common misconceptions.

Unit 2: Work and energy About this unit For our most up-to-date, mastery-enabled courses, check out High School Physics, AP Physics 1, and AP Physics 2!

¡Bienvenido a las Lecciones de física! La física es el estudio de la materia, el movimiento, la energía y la fuerza. Aquí puedes explorar videos, artículos y ejercicios por tema. Mantenemos estas lecciones …

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, …

In physics, distance refers to the total length of the path an object travels, regardless of direction, while distance traveled is the same as distance, emphasizing the actual length of the path taken.

Use a simulation to explore the motion of a projectile. Apply the kinematic equations to objects moving in two dimensions with constant acceleration in each dimension. Discover the independence of a …
