Express Physics Form 4 by Penerbitan Pelangi Sdn Bhd
Overall content is okay but I believe there are some important points are missing. Example in chapter 2 missing on pulley system and lift move up or down (R=mg+ma) and three forces in equilibrium.. Also I believe the example is inadequate in order for the student to grasp the concept and understanding. Last and not least the format is not user friendly and difficult to navigate. Regards,
