MODULE 2 DESCRIPTION
Dear learner,
Welcome to Grade 9 Physics Module!
Building on the concepts from Module 1, this second module covers the last three units of the Grade 9 physics curriculum:
Unit 5: Simple Machines
You will explore the principles and applications of simple machines such as levers, pulleys, and inclined planes. You will learn about mechanical advantage, efficiency, and the real-world applications of these machines.
Unit 6: Mechanical Oscillations and Sound Waves
This unit delves into the concepts of oscillatory motion, covering topics such as simple harmonic motion, pendulums, and wave properties. You will also study the nature and characteristics of sound waves, including frequency, amplitude, and the speed of sound in different media.
Unit 7: Temperature and Thermometry
You will learn about the concepts of temperature, heat, and thermal energy. This unit covers different temperature scales (Celsius, Fahrenheit, Kelvin), methods of measuring temperature, and the principles behind thermometers and thermal expansion.
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.
MODULE OBJECTIVES
