An electric diagram is a simple visual representation of an electrical circuit. In this video, our Sec 2 Physics PMC tutor walks us through a systematic approach to drawing an accurate electric diagram.
This video lesson our Sec 2 Physics PMC tutor explains the principle of moments. The principle of moments states that, when an object is in equilibrium, the sum of anticlockwise moments about any point equals the sum of clockwise moments about the same point.
Our Sec 2 Physics PMC tutor conducts a lesson on energy conversion and how to approach its application questions. Energy conversion is the process of changing energy from one form to another. With this lesson, the students would be able to apply their knowledge and concepts to their questions.
In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid. Our Sec 2 Physics PMC tutor breaks down the concepts to understanding sound and sound waves.
