Welcome to the 2021-22 AH Physics course. Another year, another journey together. I hope you feel that this site meets your requirements and that you can find the materials that you need.
Check out MrStewart’s YouTube channel for some great clear explanations from this course.
Using John Sharkey’s Flash Learning Virtual CfE Advanced Higher Physics these videos cover all of the unit Rotational Motion and Astrophysics. Note there have been a few changes to the Course Specifications since these were produced.
Here are some of the recordings from Virtual Flash Learning for the Rotational Motion Section. Turn off the volume if you dont want to hear from me.
AH Kinematic Relationships using the Virtual Physics
Angular Momentum-
This one has audio but you can switch it off.
Angular Motion
Rotational Dynamics
Gravitation
Space and Time
Stellar Physics
Note in the Stellar Physics video the equation for Apparent Brightness has now been changed see below
Apparent Brightness where d is the distance from the star to EarthThe thermal energy radiated by a blackbody radiator per second per unit area. This only works for Black Bodies, for other bodies the emissivity must be included. You will only be asked about black bodies in your AH exam.Luminoscity, where r is the radius of the star.
Resources: Notes and video (flash learning AH CfE Virtual Physics)
Read the notes, watch the video and answer the questions below, in a way that makes them form a good note about the subject.
What three pieces of key evidence didn’t fit with classical physics?
In 1911 Rutherford put forward his model of the atom, a) State the important features of this model b) What provides the centripetal force for the electrons in this model?
Describe black body radiation.
State two changes with the black body radiation curve as temperature increases.
Describe the UV catastrophe.
Who helped solve the UV catastrophe and in what ways?
Which piece of the photoelectric effect experiment demonstrates that energy is not transferred as waves?
From the photoelectric effect state the link between the energy of the photon and a) the frequency of the radiation, b) the wavelength
What did Bohr postulate about angular momentum?
State the formula for angular momentum in Bohr’s model of the atom, (define each term)
State the limits for the Bohr model of the atom
Explain the observation made by GP Thomson in 1920 which led to further debate on the issue.
What did de Broglie imply was the link between electrons as waves and particles?
Explain the confusion caused when looking at the double slit experiment with single particles.
What happens when you observe an electron passing through the slit?
What two quantities cannot be measured together with much certainty and why?

John Sharkey’ SHMs Virtual Physics CfE AH
John Sharkey’s Waves Virtual Physics CfE AH
This is additional support for travelling waves
Here is a nice little video on Standing Waves. Standing waves are formed when a wave interferes with its reflection to produce nodes and antinodes.
…..and here is the explanation for the standing wave video

Below are some cracking resources from Sally Weatherly, find her here!
Scientist think that the Earth is due a “Magnetic Flip” Research this starting at the link below and then answer the AH Revised question on this from the 2015 Paper Q11
Here is a Radio 4 programme talking about the consequences of a polar flip. If you want to view further programmes click on the link below.
