NSW Physics review – dot points 9.2.4

The fourth in a series of short videos, I review the dot points in the NSW HSC syllabus. I won’t go into the full details of the physics of each point, but I will touch on them discussing the nuances of each dot point.   In this video I discuss section 9.2.4 – Current and emerging understanding about time and space has been dependent upon earlier models of the transmission of light  

NSW Physics review – dot points 9.2.3

The third in a series of short videos, I review the dot points in the NSW HSC syllabus. I won’t go into the full details of the physics of each point, but I will touch on them discussing the nuances of each dot point.   In this video I discuss section 9.2.1 – The Earth has a gravitational field that exerts a force on objects both on it and around it  

NSW Physics review – dot points 9.2.2

The second in a series of short videos, I review the dot points in the NSW HSC syllabus. I won’t go into the full details of the physics of each point, but I will touch on them discussing the nuances of each dot point.   In this video I discuss section 9.2.2 – Many factors have to be taken into account to achieve a successful rocket launch, maintain a stable orbit and return to Earth

Optics – real image formation

So we know that lenses can magnify but why does a lens have the ability to display an image? In this video, I discuss why a converging lens can form real images as well as look at the factors that determine its characteristics. Using a clear explanation with animations, I help you understand the optics from a high school perspective  

superposition explained

In this video, I go through wave interference / superposition. I discuss constructive and destructive interference from a 1D perspective. For NSW students, it covers the content from the Year 11 World Communities unit (8.2), namely • describe the principle of superposition and compare the resulting waves to the original waves in sound  

Car Crash Physics

What are the Physics principles involving a car crash? How do forces, work, energy, and momentum apply? In this video I will discuss these terms in a way that will help you understand those concepts in the context of a car crashing in a wall – first at 60kph and then 100kph.  

Understanding Circular Motion

This video presents a beginner’s guide to circular motion, introducing the concept of centripetal force. It also briefly discusses the erroneous term centrifugal force. It also explains the motion with some common examples.   Clarification: in the video I mention that ‘there is no centrifugal force” What I mean is, there is no centrifugal force acting on the object spinning, like some outward force acting on the object. This is fictitious.   I the specific case of a car going around the bend, the centripetal force is provided by the road surface on the car, going inward   One could…
