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.

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.

Nuclear physics Explore how nuclei can change and emit radiation through alpha, beta, and gamma decay. Interpret half-life as the time it takes for half of sample of a radioisotope to decay. Discover …
