Rolling Motion Explained (AP Physics 1: Topic 6.5) | Rolling Without Slipping & Hard Problems

Rolling motion combines both translational and rotational motion and is a major focus of Unit 6 in AP Physics 1. In this video, we develop a complete understanding of rolling without slipping, including how velocity, angular velocity, energy, friction, and moment of inertia all work together.
We begin with the defining condition for rolling motion and carefully derive the total kinetic energy of a rolling object. From there, we apply energy conservation and Newton’s laws to solve hard AP Physics 1–level problems, including objects rolling down inclines, ranking rolling objects by speed, and determining the role and direction of static friction. We also address common conceptual traps, such as when energy is conserved, when it is not, and why static friction does no work in pure rolling.
This video is designed to give students a deep, exam-ready understanding of Topic 6.5 and prepare them for both multiple-choice and free-response questions involving rolling motion.
