In applications of rotational motion one of the most important section is rolling motion and variety of problems are framed on rolling motion and its applications. Rolling motion problems are divided in two categories – Pure Rolling and Rolling with sliding. Majority of problems which are asked in pre engineering exams are based on pure rolling and its applications. Here for in-depth understanding of pure rolling and its applications, watch the illustration videos given below.
