SCIENCE 9 QUARTER 4
At this level, you are already equipped with some basic ideas in Physics from your previous learning in Grade 7 and 8. You were able to describe motion and the forces that affect it and explained why objects move the way they do. Heat and temperature is an exciting topic that you also explored. As a student, you acquired basic concepts ou n how heat is transferred. You also gained a greater appreciation of the natural phenomena of light and sound through the concept of waves, and understanding of the laws of optics. From these concepts that you learned, you were able to understand your environment and the different changes happening to it.
Now, you are going to do Physics more mathematically. This will allow you to unlock more ideas about your physical environment. At the same time, this will improve the mathematical skills you gained in your previous grade levels, by finding new ways of applying math. Four modules will be presented to you for a deeper understanding of forces, motion, and energy.
In Module 1, you will learn how to describe uniform motion mathematically. With forces and motion, you will be able to apply Newton's Laws of Motion to practical problems in free-fall, projectile motion,and understand the concepts of impulse and momentum. With these, you will find out how ideas in Physics can help you better in our favorite sports.
In Module 2, you will tacarkle work, power, and energy and explain how they are related to one another. You will learn how conservation of energy can be used to describe the motion of man-made objects like roller coasters, and the rush of water in waterfalls.
In Module 3, you will encounter topics in heat and work and how these two relate with each other. With the basic concepts on heat and work, you will understand how heat is converted to work, and work to heat.
In Module 4, you will learn how electrical energy is generated and transmitted. You will further develop your understanding of the transmission of electricity from power stations to your homes. From these concepts, you will be able to gain further insights on the transformation of energy that takes place in hydroelectrical power plants.
