## Newton’s law of universal gravitation equation

Dr Victor decides he wants to be rich and powerful. He steals a planet and plans to crash it into earth so he can save time and money mining it for the endangered metal, Gallium. Bug-man must use the laws of universal gravitation to save the day.

## Torque HSC Questions that will scare you

Torque HSC questions are renowned for being scary. One of my students who had never lost a mark in a HSC physics internal exam thought torque questions were going to be his downfall. Whilst the concept of torque is rather simple, realistically just a mathematical formula to explain what to do to open a door,Continue reading “Torque HSC Questions that will scare you”

## Circular motion HSC Questions

Ever wondered why the wheels on a car appear to rotate backwards when you see a video of it going extremely fast? My friend, this is due to circular motion and the frames per second of the video. After today’s lesson you will understand uniform circular motion and will have seen Circular motion HSC Questions.Continue reading “Circular motion HSC Questions”

## Charged Particle in Electric and Magnetic Fields

Let’s look at charged particles in electric and magnetic fields. Okay, so imagine you’re in a giant game of laser tag, and you’ve got your trusty laser gun at your side. But instead of just shooting lasers, your gun can also emit charged particles that you can use to your advantage. Now, let’s say you’reContinue reading “Charged Particle in Electric and Magnetic Fields”

## Kepler’s Laws and must see HSC Questions

Kepler’s Laws provided early astronomers with a useful framework for understanding planetary motion. Jump to HSC Questions Johannes Kepler described his laws of planetary motion between 1609 and 1619, he was one of the first people to like to the skies and encapsulate the behavior of stars, moons and planets into laws. The first lawContinue reading “Kepler’s Laws and must see HSC Questions”

## Inclined plane and banked Curve HSC Questions

Banked Curve HSC Questions often require students to approach the problem from a mathematical perspective. The good news is this can be learnt using a method which repeatable and can be systematised. This way you get the right answer every time. Jump to the exam-style questions here. An inclined plane and banked curve problem canContinue reading “Inclined plane and banked Curve HSC Questions”

## The Motor Effect

The motor effect is when a current carrying conductor creates a magnetic field. This magnetic field is circular and will interact with other magnetic fields. As a result, the wire experiences a force. The motor effect is the reason a motor works, the interaction of a wire coil with a magnetic field results in rotationalContinue reading “The Motor Effect”

## How to Build a DC Motor

Building a DC motor is often an assessment task in the HSC Physics Course. The truth is it is easy to do well in this assessment if you follow a couple simple videos and use some critical thinking to get the best result. Often times when teachers are marking, we are looking for novelty toContinue reading “How to Build a DC Motor”

## Experiment: Parallel Current Carrying wires

Parallel current carrying wires demonstrate that a wire has a magnetic field when there are electrons running through it. These magnetic fields can interact with one another. In this experiment we will see this first hand. After today you will: Learn. As we saw in the 𝐹 = 𝑙𝐼𝐵sin𝜃 lesson, a current carrying conductor createsContinue reading “Experiment: Parallel Current Carrying wires”
