Introduction to AP Physics C: Mechanics

0:02(rope snaps) - [Instructor] How does NASA train astronauts for a weightless environment here on earth? How do we figure out the minimum speed needed to escape Earth's gravity? And why do the ice skaters spin faster as they pull their arms in? Welcome to AP Physics C: Mechanics, an introductory college level calculus-based mechanics course.

0:26Here, we'll answer questions like these and more, both intuitively and rigorously by building mathematical models. At its core, physics is about observing patterns, describing them with mathematical models, and then using those models to predict the future, and that's exactly what we'll do in this course.

0:46We will start with kinematics, where we learn how to describe motion. We will use limits and derivatives to represent rate of changes and integrals to accumulate those changes, and then extend those ideas into multiple dimensions. Then we'll move to dynamics, where we ask the deeper question, what causes motion to change?

1:09This will take us to forces and Newton's laws, giving us the tools to model gravity, friction, springs, and more. From there on, we'll develop some powerful ideas like energy and momentum. These not only help us connect forces and motion more elegantly, again, using derivatives and integrals, but also let us analyze complex situations like collisions without having to track every single detail.

1:37And then we'll extend these ideas to rotations, where we'll build concepts like torque and angular momentum, which will help us analyze everything from rolling objects to orbiting satellites. And finally, we'll explore oscillations and harmonic oscillators, helping us understand springs and pendulum systems.

2:00So whether you're preparing for an AP exam or taking an introductory college physics course or, you know, just simply curious about how we, as humanity, unravel the rules of this physical world, well, then this course is for you. Because you won't be just watching videos, you will actively engage with the ideas through our interactive articles, where you can check your understanding thoroughly.

2:27You will also work through a wide range of practice questions. There are multiple choice questions, questions where you graph on your own, questions where you rank different options, and even problems where you derive expressions yourself. These will help you prepare for free-response questions.

2:44And if you get stuck, there are hints to guide and nudge you towards the right direction. And by the way, many of these questions include reference information drawn directly from the AP Physics 1 equation sheet, you know, the same sheet you'll have access to during the AP exam.

3:01So again, welcome to AP Physics C: Mechanics. I'll see you inside.
