Physics Grade 9: Semester 2

Description

Dear learner,

Welcome to Grade 9 Physics Module! This module covers the final three units of the Grade 9 physics curriculum: Through these units, you will gain a deeper understanding of the physical principles that govern everyday phenomena. As with Module 1, this module combines theoretical knowledge with practical examples to enhance your learning experience and prepare you for further studies in physics. Remember, online learning requires self-discipline and active engagement. Take advantage of the resources and support available to you, and don’t hesitate to reach out to your instructors for guidance and assistance.
