Amazing website, really really helpful. ), glad you’ve found my notes helpful. I got a 7 fortunately. Physics. A Type II Supernova is a supernova that is classified as having hydrogen lines in its spectra that are made by the explosion of a very large star. Hi Aryan, glad you’ve found the notes helpful. http://hubblesite.org/hubble_discoveries/dark_energy/de-fate_of_the_universe.php. After the Big Bang, the universe began expanding outwards. I got a 7 and here’s how you can too! Further fusion only takes place in heavier stars, otherwise the pull of gravity forces the star to contract and cool to a red dwarf. Hey David! About Us. ib-physics.net is a student initiative to provide free material to help international students prepare for the IB exams. Some of these might be obvious things, but I think it’d be useful to have them nonetheless! While I usually study my butt off and shoot for a perfect score, I have been accepted into university, finished my other curriculum, and just need my IB diploma at this point. Hi Athul, I might know a site that may be helpful for Physics. Nucleosynthesis requires high speed collisions and high temperatures. ib-physics.net is a student initiative to provide free material to help international students prepare for the IB exams. In other words, the halo of our galaxy is filled with a mysterious matter of unknown composition and type known as dark matter.

International Baccalaureate IB Physics SL Past Papers | Standard Level Really helped me throughout IB. The formation of elements heavier than iron and nickel requires the input of energy. Save for later. Free Notes / Resources EE3. However, homogenous does not mean that all regions of space should appear identical or be smoothly filled with particles. does it have all the things required to answer all questions? Vectors (with arrows pointing in the same sense) forming closed polygons add up to zero. The idea of a uniform universe is called the cosmological principle. hello David, Standard Grade Physics Revision Notes; U. • Hands-on-skills tasks for graphing to hone key skills for the IB Physics Astrophysics option. Great work! Solar System: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.. Interstellar: It is referred to as a the space between stars, roughly 5-20 Light-years(Ly) apart..

All images are under copyright that allows them to be shared. For systematic error’s explanation: “*Biased* in the same direction, the results are *always too large or too small*.” Because of eLearning, I have been working on animating slides and creating video lectures for the entirety of the IB Physics curriculum. When the white dwarf reaches 1.4 solar masses, or about 40 percent more massive than our Sun, a nuclear chain reaction occurs, causing the white dwarf to explode. Hi Julia, hope you passed your exams lol. However, I managed to save some Powerpoints notable to this community and share it with you guys. A deuterium and a hydrogen fuse to create helium and a gamma particle. Email. There are two aspects of the cosmological principle: How do we measure the amount of mass in the universe? Hi David, I’m just asking if you upload lessons for the curriculum of grade 9 pre-ib (chemistry and physics)? The rotation curve of the galaxy indicates a great deal of mass but these masses cannot be observed.

I don’t think I’ll be doing any additional topics since I’ve graduated quite a while ago. D.1.2.17 The diagrams represent three positions, X, Y and Z, of a spectroscopic binary star system which contains stars A and B. Another deuterium and a hydrogen fuse to create helium and a gamma particle. Found a minor formatting error: under ”Graphs describing motion” in Topic 2, the graph header isn’t made to be in the same format as the rest of the graph headers. Happy revising! During this time, photons could not travel undisturbed through the plasma because they interacted constantly with the charged electrons and baryons, in a phenomenon known as Thompson Scattering. The main process for energy production in a star is nuclear fusion of hydrogen to helium. The universe is dominated by dark energy. First assessment 2016. Thank you David. You’re right. d = 2, the = 1. d = ˚ = ≈ = .. ′′ = sun a Type “Relativity” and it will bring you to all of the material for Relativity.If you are looking for overall study material for the IB Physics Exam, skip to the end of this guide to the Overall Reviews section for great ove… To find the distance to the galaxy that contains the supernova, scientists just have to compare how bright they know the explosion should be with how bright the explosion appears. However, the course should be accessible to students with just a general introduction to physics. It should be corrected now, thanks. If P 1 is the lung pressure, P 0 is the atmospheric pressure, then if the difference is ‘h’ then lung pressure can calculated as follows.. P 1 = P 0 + hρg.. All the best. All Astrophysics courses require basic mathematical skills and certain mathematical techniques. Should be correct now. Hi, I’m David. Hi Chris, glad that you’re using my notes. 5.3 Electric Cells. The IB wishes to thank the educators and associated schools for generously contributing time and resources to the production of this guide. 5. Mathematics . Hey David, thanks a lot for all the physics content. where H is the Hubble constant for a given cosmological time (such as the present). The current critical density is approximately 1.06*10^-29g/cm^3. The hydrogen lines come from the hydrogen-rich outer layers of the star as the star explodes. Scientists once thought that it would eventually run out of the energy, slowing down as gravity pulled the objects inside it together (Big Crunch). One of the stars in the system must be a white dwarf star, the dense, carbon remains of a star that was about the size of our Sun. Current and Drift velocity I=nAqv. Hi Zaid, I’d recommend thoroughly studying the exam materials before jumping to past papers. Hi Meet, glad you’ve found my notes useful, even as a college student. Roughly 80 percent of the mass of the universe is made up of material that scientists cannot directly observe. Hi, David. The link doesn’t seem to be working.

MAY 2019 Grade boundaries for Diploma programme coordinators This document provides the component and overall grade boundaries for IB Diploma Programme courses with more than 100 candidates in MAY 2019. For random error’s explanation: “Repeated measurements show a *spread of values*, some too large and some too small, and it is *unbiased*”. But studies of distant supernovae revealed that the universe today is expanding faster than it was in the past, not slower, indicating that the expansion is accelerating (Big Rip). ASTROPHYSICS AND COSMOLOGY J.

Man, I cannot stress how helpful these notes have been to me, I consider myself to be below average in physics, mostly because i am really bad at making notes and I do not understand my physics teacher. Known as dark matter, this bizarre ingredient does not emit light or energy. D.4 – Stellar processes The Jeans criterion Stars form when a portion of interstellar cloud collapses gravitationally. For instance, if you want to study Relativity, use Command + F to bring up the search function. I noticed a mistake on topic 2 regarding Newton’s second law where it says that Force is inversely proportional to mass. ib-physics.net is a student initiative to provide free material to help international students prepare for the IB exams. Note: All planets beyond Mars are gas giants; i.e. 1 F.1 Introduction to the Universe. Some of the … This publication is one of a range of materials produced to support these programmes. The Jeans mass criterion is determined by asking when the magnitude of the gravitational potential energy exceeds the magnitude of the gas’s kinetic energy. The hydrogen around the core burns more fiercely and causes the outer part of the star to expand and cool down. The required material for the IB Physics SL Option E. Taken from the "First Examinations 2009" IB Physics Guide. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. SPREAD THE WORDS. Hey David, my exam is in two days, and I was stressing out crazy, but then I found your website. shouldn’t it be “µk”? Hey ! Hi, David, do you have an app on apple store?
