Work, Energy, and Power: Crash Course Physics #9

If you have any feedback, let me know in the comments down below! Hi, David. I used your site to review my exam, and it is very good. I actually take notes from your notes on this site, even. However, it seems like the version of the formula booklet you have here is outdated.

Apart from that, loved your site, and your notes! David, you are magic. I am going to be going to Grade 11 in September, and I already feel ready to tackle this subject: your notes are very nicely organized and super helpful: thank you for taking the time to do this! Thanks for this app. Which of these classes you took?

I would appreciate if you make similar apps for other subjects like Maths. For maths, I suggest you work through past paper problems. There is an error in Option D:Astrophysics.

Wavelength of cosmic background ratiation increases overtime, it does not decrease. Hey David, thanks a lot for all the physics content. Really helped me throughout IB.

IB Physics Unit 2 (Mechanics/Kinematics) Test with Marking Scheme

Keep up the good work. Hey David! First of all, thank you so much. Glad that you found the notes useful and yes you are right. I believe it is meant to be in header 2 format, but it is just regular text sizing at the moment.See the guide for this topic. Velocity is a measure dependent on the motion of the observer. The relative velocity of A to B is equal to the vector subtraction of the velocity of B from the velocity of A. This value does not depend on the mass of the object.

Take note that acceleration is a vector and thus has a direction. An object is said to undergo projectile motion when it follows a curved path due to the influence of gravity. Air resistance limits the maximum velocity an object could attain from free-falling. For example:. Objects are represented as a point mass to enable the representation for forces as arrows in free-body diagrams.

On a free body diagram, forces acting on an object are represented as arrows which stem from a point mass. The length and direction of the arrows corresponds to the magnitude and the direction of the forces acting on the body of interest. A body is said to be in translational equilibrium if it the net force acting on the body is zero. This means the body is either at rest or travels at constant velocity. Friction is a non conservative force which opposes motion.

If there is no motion, then there will be no force caused by friction. For two solid surfaces moving over each other, the friction will be affected by the nature roughness etc of the two surfaces. However, the surface area and velocity of the object does not affect the friction.

There are also two types of friction for solid surfaces: static friction and kinetic friction. Static friction is that which stops objects from beginning to move.

Kinetic friction is that which slows objects down when they are moving. Static friction is always larger than kinetic friction. The gravitational potential energy GPE of an object changes with its height and is given by the equation. Elastic energy is potential energy stored as a result of the deformation of an elastic object such as the stretching of a spring and is given by the equation. Energy can neither be created nor destroyed; it can only be changed from one form to another. Efficiency is the ratio of useful energy output to energy input as a percentage given by the equation.

The law of conservation of linear momentum states that the sum of initial momentum is equal to the sum of final momentum in a closed system and can be given by the equation.International Baccalaureate IB. It is still probably the most challenging class I have ever taken even including my college coursesbut I got a 6 on the exam, so trust me—it's doable. Because of the COVID coronavirus pandemic, all IB exams for May have been canceled and coursework deadlines have been extended for schools that have closed.

Follow these three tips to get the most out of your notes. If you learn about a new topic in class and don't quite understand it, it can be be tempting to just forget about it and move onto the next lesson.

Don't do this! The longer you wait to go over the topic, the harder it will be to actually understand it because you will have forgotten more of what you learned about it in class. There are so many topics you cover in IB Physics that if you do not keep up with the material during the school year, you will find it nearly impossible to catch up. Don't wait until the last minute to begin your review.See the guide for this topic.

When the electrons within an atom jump from one atomic energy level to a lower energy level, energy is released in the form of light. Likewise, light is absorbed when the electrons within an atom jump from one atomic energy level to a higher energy level. The amount of energy absorbed or released can be calculated by the difference in energy eV between the two energy levels. An alpha particle is a helium nucleus.

A beta particle is an electron or a positron. Different isotopes of a given element have the same atomic number atomic number defines the type of element but different mass numbers because they have different numbers of neutrons.

It is defined as one twelfth of the mass of a carbon atom. Quarks and gluons massless subatomic particles that transmit the force binding quarks together in a hadron are color-charged particles. Similar to electrically-charged particles which interact by exchanging photons in electromagnetic interactions, color-charged particles exchange gluons in strong force interactions. Note that color charge has nothing to do with visible colors.

It is just an expression. When two quarks are close to each other, they exchange gluons and create a strong color force field that binds quarks together. The force field gets stronger as the quarks get further apart.

Quarks constantly change their color charges as they exchange gluons with other quarks. There are 3 color charges and 3 corresponding anti-color charges. Just as mixing red, blue, and green visible colors yield white, mixing red, blue, and green color charges yield color neutral.

Color confinement is a phenomenon that color-charged particles cannot be isolated singularly and therefore cannot be directly observed. The color-charged quarks are said to be confined in groups hadrons with other quarks which composite to color neutral and cannot be distinguished separately. This is because the color force increases as the color-charged quarks are pulled apart.

TL;DR : Color confinement or quark confinement is the phenomenon when isolated quarks and gluons cannot be observed. In addition to the three generations of leptons and quarks see previous section Quarks, leptons and their antiparticlesthere are four classes of bosons and an additional highly massive boson called the Higgs boson.

This particle was proposed in to explain the process which particles can acquire mass and was identified with the Large Hadron Collider LHC.

It was built by CERN in collaboration with over scientists and engineers from over countries along with hundreds of universities and laboratories.

As an electron makes a jump from one energy level to another, energy is absorbed or released in the form of a photon. The amount of energy absorbed or released is equal to the difference between the discrete atomic energy levels and is also quantized. The energy of a photon is dependent on its frequency. Therefore, only photons with frequencies which correspond to the differences between the atomic energy levels can be absorbed or released by an atom.

physics unit 2 ib

These frequencies appear as spectral lines in the emission and absorption spectra. The existence of discrete energy levels called atomic energy levels can be supported by the emission spectra and the absorption spectra of atoms.

Transitions between energy levels When the electrons within an atom jump from one atomic energy level to a lower energy level, energy is released in the form of light. Radioactive decay Radioactive decay refers to the spontaneous random process by which particles or electromagnetic radiation is emitted from an unstable nucleus.They're matched up with a great team from Alabama.

That's going to be a fun one to watch. Georgia, I'm going with Georgia to beat Oklahoma just because of my cousin (Nick Chubb). That leaves Georgia vs. Clemson in the national championship game. Out of that one, UGA. See that Chubb name with the national championship trophy. I don't think anyone is going to be able to run the ball consistently on them. I've watched Clemson a lot. They're fun to watch. They didn't want us to be here so let's tell them why we're here.

I know I'd have a little edge about me if they didn't want me to be in there. Then we get in there and we're playing Clemson, the team we lost to in the final minutes last year.

I'd have a little edge about. I at least think they'll beat Clemson. I think coach (Dabo) Swinney has done a great job with the culture there to do what he's done in a relatively short period of time just winning ballgames and staying on top. Clemson is looking good as well. College football is crazy, man. Anybody can be beat on any given day so you have to hold onto your seat and watch what happens. I have my guy, Dexter Lawrence at Clemson.

We played high school ball together so I have to go with Clemson. I watched them play all the time, Georgia, I've seen them play all the time. There are a lot of good teams in there right now. I'm a Georgia Dawg.

Oklahoma "One reason: Baker Mayfield. Clemson "They're ranked first in defensive efficiency and their defensive line is unbelievable. Clemson "Well my brother is a linebacker at Clemson, so I have to go with them, for his sake. Georgia "Georgia, all the way.
