# AP Physics C: Mechanics What is Physics?

Welcome to the Mechanics section of the AP Physics curriculum! This part of physics serves to give you a basic understanding of the world around you, and will give you the mathematical and conceptual mind needed to observe and predict basic occurrences in the physical world. To understand physics, we first have to delve into the nitty-gritty of what matter is and the properties that it has such as mass. From there we can calculate from those properties like how much force it exerts on another object. Of course there are other factors, and we will learn about these in the videos to come, but this will be a great starter video to get you prepped for the course ahead. Best of luck!

I have a more general question about this course.

Would this course, along with allowing me to be able to take the AP exam of course, also help me with advancing to the Semi-finalists/USAPHO for the f=ma physics exam? Thank you for the help!

Hi, Mr. Fullerton!

I have been studying AP Physics C on my own while taking another algebra-based physics class at school, and I am currently reading a calculus-based textbook as well as doing a fair portion of end-of-chapter problems. I feel that I understand the concepts well after finishing the book problems, but when I try out the AP FRQs for that specific chapters, I apparently make a lot of mistakes (and I feel that the AP problems are strange depsite they are testing the same concept).

So is there really some difference between the AP problems and the textbook problems? And should I abandon the textbook problems and only use the old AP FRQs, or keeping doing both of them?
