Welcome to Physical Science Grade 11/12 Alternative Delivery Mode (ADM) Module on the topic Models of the Universe (Greek Astronomy to Kepler)!
Our hands are the most represented parts of the human body. It is often used to depict skill, action, and purpose. With our hands, we create, accomplish and learn. Hence, you are capable and empowered to successfully achieve the relevant competencies and skills at your own pace and time. Your academic success lies in your own hands!
This module was designed to provide you with fun and meaningful opportunities for guided and independent learning at your own pace and time. You will be able to process the contents of the learning resource while being an active learner.
This module was designed and written with you in mind. It aims to help you master the Aristotelian and Galilean concepts regarding motion, uniform acceleration, and the distinction between Newton’s first law of motion to Galileo’s assertion. The language used recognizes the diverse vocabulary level of students. The lessons are arranged to follow the standard sequence of the course.
The module consists of only one lesson:
- Lesson 1 – Aristotelian and Galilean Conception of motion, Uniform acceleration and Newton’s first law of motion and Galileo’s Assertion
After going through this module, you are expected to:
1. Compare and contrast Aristotelian and Galilean conceptions of vertical motion, horizontal motion, and projectile motion;
2. Explain how Galileo inferred that objects in vacuum fall with uniform acceleration, and that force is not necessary to sustain horizontal motion;
3. Explain the distinction between Newton’s 1st Law of Motion & Galileo’s assertion that force is not necessary to sustain horizontal motion; and
4. Cite practical applications of principles involving motion in our day to day living.
