The value of practicality by educators and students shows that the worksheet developed is categorized as very practical with a proportion of 90.24%. Based on these results, the worksheet with material on dynamics of rotation and balance of rigid bodies that has been developed is categorized as valid and practical. After obtaining a valid and practical product, the product is suitable for use in assisting the learning process.
