### Text Books

• D. Halliday, R. Resnick, K. S. Krane, Fundamentals of Physics , Part 2 - The course book, a colorful book with illustrations and photos. This book is a good foundation the course basics and includes exercises and explanations (English)
• האוניברסיטה הפתוחה, אדוארד מ. פרסל ;חשמל ומגנטיות - Translation of the relevant book from the Berkeley series, over the course level (hebrew)
• The Feynman lectures on physics Vol. 2 - Thorough reference book of one of the greatest physicists who knew also how to explain an unusual manner. Not easy at all but a worth the effort. It is not a usual book! (English)

### Remarks

• All the courses in this category have the same syllabus, i.e. the lecture material is the same.
• Enhanced Course means that the the class/home set of problems contains more difficult questions.
• Reinforced course is a regular course with an extra hour. The extra hour is used *not* to cover additional material, but to have the possibility to go slower, add more explanations, examples etc.

## Course Policy:

• הציון הסופי בקורס יחולק לפי - 85% מבחן ו 15% בוחן אמצע.
• בוחן אמצע יהיה מגן
• עובר בקורס יהיה ציון משוכלל של המבחן והבוחן, ציון בוחן ילקח בחשבון אם יהיה גבוהה מציון המבחן
