Description
Dear learner,
Welcome to Grade 9 Physics Module! This module covers the final three units of the Grade 9 physics curriculum:
Unit 7: Temperature and Thermometry – Study temperature scales, thermal energy, and thermometers.
Unit 5: Simple Machines – Learn about levers, pulleys, inclined planes, mechanical advantage, and efficiency.
Unit 6: Oscillations and Sound Waves – Explore simple harmonic motion, wave properties, and sound characteristics.
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.
