Cora Henderson's Physics Channel
United Arab Emirates
Приєднався 25 жов 2011
This channel was started as a way to support my IB Physics and HS Physics students to use Logger Pro Video Analysis at home during the pandemic. It has grown since then to include explanations of the content. Please share with friends. I do not plan to charge for these videos, so please share with friends. I do ask that I am given credit for my work so these may be linked into a site, but please come back here to watch.
Hertzsprung Russell Diagrams
This video will explain the Hertzsprung-Russell diagrams in terms of showing different kinds of stars. It will go through the logarithmic scales and show you where to find our Sun. At the end there are 3 worked examples. This is part of the IB Physics Syllabus in E.5. It is relevant to both HL and SL students.

Orbital Motion
Переглядів 1521 день тому
In this video, I will go through how to calculate the orbital speed and period for a satellite. It starts with the theory and then there are 2 worked examples using centripetal force and the Universal gravitation equation. This is part of the International Baccalaureate and is relevant to both SL and HL students.
Fusion in Stars
Переглядів 19Місяць тому
In this video, I will go through the proton-proton cycle of fusion in the Main Sequence Stars. This is part of E.5 in the IB Physics Syllabus and is relevant to both SL and HL students. Like always, the video will start with theory and will end with some worked through examples.
Main Sequence Stars and Evolution of Stars
Переглядів 43Місяць тому
In this video, I will go through the processes happening in a Main Sequence Star and how it evolves over time to become different classes of stars until it reaches a white dwarf or black hole depending on its initial mass. This is part of E.5 in the IB Physics Syllabus and is relevant to both SL and HL students. Like always, the video will start with theory and will end with some worked through...
Gravitational Fields
Переглядів 10Місяць тому
This video will discuss how to create gravitational field lines and how to calculate gravitational field strength. The first part has a review of the theory and then there are 3 worked exampkes. It is part of the IB Physics Syllabus and is relevant to both SL and HL students.
Kepler's Three Laws
Переглядів 28Місяць тому
This video will go through Kepler's 3 Laws. It starts with the theory and then has worked examples. This is part of the IB Physics Syllabus and is relevant to both HL and SL students.
Enhanced Greenhouse Effect
Переглядів 313 місяці тому
This video will go through the effect of increasing the concentration of Greenhouse Gases to the atmosphere. It will calculate what the average temperature of the Earth would be without the absorption and re-radiation of energy by these gases and describe some of the positive feedback loops that we are creating. This is part of the IB Physics Syllabus and is relevant to both HL and SL students.
Emissivity and Albedo
Переглядів 1003 місяці тому
This video will go through how to calculate using emissivity and albedo including examples with melting ice and power emitted by a heater in a room. This is part of the IB Physics syllabus and is relevant to both HL and SL students. This is important background for the Enhanced Greenhouse Effect.
Luminosity, Brightness and Solar Constant
Переглядів 393 місяці тому
This video will distinguish between the luminosity (power) and the brightness (intensity) of a star. It will also show you how to determine the solar constant of the Sun (brightness of the Sun at the distance of the Earth). This is part of B.1 in the IB Physics syllabus. It is relevant to SL and HL students.
Blackbody, Wien's Law and Stephan-Boltzmann Law
Переглядів 383 місяці тому
In this video the concept of a blackbody will be used in terms of stars. It will cover how the peak wavelength given off is related to the temperature (Wien's Law) and how the luminosity (power of a star) and brightness (intensity) are affected. This is relevant to both SL and HL students in the IB Physics course.
Conduction Convection and Radiation
Переглядів 534 місяці тому
This video will use experiments and real life examples to show how thermal energy (heat) can be transferred. This is part of the IB Physics Syllabus in B.1 and is relevant to SL and HL students.
Phase Angle and Simple Harmonic Motion
Переглядів 404 місяці тому
This video will tell you how to get the phase angle from the equation of the sine curve as well as how to determine the phase difference between two curves on a graph. This is part of the IB Physics syllabus for Higher Level students only.
Calculating Energy in Simple Harmonic Motion
Переглядів 494 місяці тому
This video starts with a quick review of the conditions needed for simple harmonic motion. The changes of energy are talked about first qualitatively and then the equations are given so that the examples have calculations. In the IB Physics syllabus, SL students only need to be able to talk about the energy qualitatively while the HL students also have to do the calculations.
Waves Basics
Переглядів 474 місяці тому
This video will discuss some of the basic theory of transverse and longitudinal waves. It will review the difference between wave motion and the motion of the particle as well as go through the terminology needed to describe waves. There are some easy sample questions at the end to check your understanding. This is part of Theme C.2 in the IB Physics Syllabus, though it may be expected knowledg...
Motion Graphs of Waves
Переглядів 494 місяці тому
This video will go through displacement-distance graphs and displacement-time graphs for waves. There are 2 examples of how to use data from the graph to answer questions. This is part of C2. Wave Model from the IB Physics Syllabus. It is relevant to SL and HL.

Tips for Creating a Research Question first exams 2025
HIiiii i need urgent help in the graphing software. I dont have logger pro how else can i do the same?????
Well, you can get a 30 day trial for LoggerPro if you wish. You can still do all of the steps and do the graphing of the different calculated values on Google Sheets or MS Excel. They call a line of best fit a trend line. Just make sure you use a scatter graph and not a "line graph" (which always gives a straight line). Don't include units with your values or you will get a "line graph" by default. Hope that helps.
Hello Ms. Cora. Thank you so much for this video. I just had a question. My IA question is about salt concentration of water and how it affects the heat loss of water. I think that it is a very basic question and I want to improv it. Could you give me suggestions to find a better experiment? Thank you so much.
Thank you for the compliment. I have been thinking about your IA. It is difficult without knowing details, but it did remind me of the old fashion way of making ice cream. They used to add salt to ice that they packed around the milk mixture to cool it faster and also freeze. Perhaps that can spark an idea on how to make an interesting design to collect your DV. I do have a playlist for IAs as well.
Can I use this for my assignment project?
what kind of project?
@@corahendersonsphysicschannel the same as the title of this video
I hope u done all ur research well cause I am just going to summarise this can you assure that
this video made me get it in the first 2 min, amazing
Thank you.
excellent video
Thank you very much!
Nice explination ❤️
Thank you 🙂
