Energy stores and transfers are one of the really big ideas in physics and this is also a topic that AQA has announced will be in Paper 1 for the Trilogy examination this month. With that in mind, I have created a new revision resource that you can use to check your knowledge and understanding. … Continue reading Energy Revision – new resource
Electrical Energy Calculations
The equation for electrical energy is tricky because it contains four components whereas many of the common GCSE equations contain only three components - or can easily be reduced to three because one of the components can be treated as a constant. The best way to handle a four-component equation is to fill-in the values … Continue reading Electrical Energy Calculations
Check your Knowledge
The ability to recall key facts and the relationships between those facts is an important part of learning in any context. As we reach the end of the two modules covering Waves and the Electromagnetic Spectrum it is important that you check how much you can remember of the content that has been covered. To … Continue reading Check your Knowledge
Representing Waves
Waves on water are very familiar, especially here in Jersey, but to analyse waves properly we need an instrument that offers suitable measurement features. The instrument that we use is called a Cathode Ray Oscilloscope (CRO). You have seen sound waves on a CRO screen in the lab and you can revisit this learning online … Continue reading Representing Waves
Observing Waves
Although human vision relies on visible light, we can't actually see light itself. Physicists have therefore modelled the behaviour of light using waves that can be seen, especially water waves. In the lab, we would be able to observe this using a ripple tank but you can currently experience this experiment from home using resources … Continue reading Observing Waves
Acceleration
Acceleration is the rate of change of velocity. It is calculated by finding the change in velocity and dividing that number by the time taken for the change to occur, as shown in the word equation below; acceleration = (final velocity - initial velocity) / time taken This can be written in symbols using either … Continue reading Acceleration
