## Topics Covered:

- Moment of a Force
- Principle of Moments
- Centre of Gravity & Stability

### About this course

**Are you a student taking the GCE “O” Level Pure Physics examination? Are you having difficulties understanding the concepts of the Turning Effect of a Forceand not able to follow what your teachers taught in school? If so, then this course is for you. **

**This course is carefully crafted to help students achieve the learning outcomes detailed in the GCE “O” level Physics syllabus (6091).**** It is designed to make the learning process simple, fast and effective.**

**Every lesson consists of a short video that explains the concept with animated illustrations using everyday-life examples. At various learning milestones, quizzes with questions of gradual difficulty levels are provided to enable students to test their understanding and reinforce their learning. Throughout the course, students will be given exam preparation tips, advised on commonly made mistakes and misconceptions and taught the skills of how to correctly answer GCE O Level questions. By the end of the course, students will be well equipped with the knowledge required for examination.**

## What you will learn

- describe the moment of a force in terms of its turning effect and relate this to everyday examples

- recall and apply the relationship moment of a force (or torque) = force × perpendicular distance from

the pivot to new situations or to solve related problems

- state the principle of moments for a body in equilibrium

- apply the principle of moments to new situations or to solve related problems

- show understanding that the weight of a body may be taken as acting at a single point known as its

centre of gravity

- describe qualitatively the effect of the position of the centre of gravity on the stability of objects

### How you will benefit from this course?

- Learn each concept easily in under 10 minutes
- Learn at your own pace.
- Visualise and grasp the concepts through animated illustrations and everyday-life examples
- Gain confidence in exam preparation through a guided program of solving questions of gradual difficulty levels and acquire the skills to solve GCE “O” level examination questions
- Get tips on commonly made mistakes and be corrected on misconceptions
- Choose how you want to learn, by concepts or go straight into testing your understanding by solving questions or pick specific topic to learn
- Learn from questions & answers posted by other students and share your knowledge or post your questions in the comments section below each lesson.

### Who this course is for?

- Secondary 3 and 4 students preparing for GCE “O” Level Pure Physics examination students
- High School students who need to understand the concepts of Moments, Centre of Gravity and Stability.

### Requirements

- Basic knowledge of forces.
