Potential Energy Problems Worksheet in a learning medium can be used to check pupils skills and knowledge by answering questions. Because in the Scholar Worksheet about 90% of the contents of the whole book are questions, both multiple choice and answer issues that are not available. While the remainder is made up of short summary of the subject matter. Using worksheet, educators no longer have to trouble to get issues or questions. With the media the instructor is only required to concentrate on giving a optimum understanding of the specified subject. For the evaluation and test of learning outcomes, the instructor only wants to inform and strong the questions already obtainable in the worksheet. Because just about the worksheet acts as a guide for pupils in carrying out learning jobs both independently and in groups.
