[very-uncorrect]

We're getting all the equations on the equation sheet for the physics exam and I'm so fucking happy because there's like 30 of them and it was the hardest thing to revise for physics before now

aqa after saying that there wouldn’t be circuits or hazards of radioactive emissions then putting in circuits and hazards of radioactive emissions:

Way to remember nuclear fission and nuclear fusion for anyone who gives a fuck

Nuclear fission: If Quagmire entered the room,everyone in the room would run away. This would create a unstable amount of people bumping into each other. Just like with fission,when a neutron hits a unstable nuclei,causing it to spilt apart.

Nuclear fusion: If Edd Gould would to come back from the dead and put himself into a room,everyone would come towards Edd and hug him. This would create a huge group of people close together.Just like fusion,when a nucleus is fused together.

The fact that aqa is only giving triple physics students 9 extra marks despite there being multiple high mark questions not on the topic list i.e static electricity, is so messed up

Suck my dick aqa don't need your fucking marks anyway <3

manifesting doing well on physics solely because advanced info was wrong but also i didn’t revise enough so it cancels out

Energy Stores ⚡🏪 - Physics

Magnetic energy store - the energy stored when poles attract or repel 🧲

E.g.: Fridge magnets, compasses, maglev trains which use magnetic levitation

Internal (thermal) energy store - the total kinetic and potential energy of the particles in an object aka the kinetic energy/vibrations of particles. Hotter object 🔥-> MORE internal energy (particles vibrate faster)

E.g.: Human bodies 🤾🏼, hot coffees ☕, stoves or hobs. Ice particles 🧊 too, just they vibrate slower.

Chemical energy store - the energy stored in chemical bonds, like the bonds between molecules

E.g.: Food, fuel, certain chemicals found in batteries

Kinetic energy store - the energy store of a moving object

E.g.: Any moving object, really

Electrostatic energy store - the energy stored when charges (protons+ & electrons-) attract/repel

Elastic potential energy store - the energy store of an object that is being squashed/stretched

Gravitational potential energy store - the energy of an object above the surface of the Earth 🌍 - the higher the object is, the higher its gravitational potential energy

E.g.: Planes ✈️, cups on tables 🍺, birds 🕊️, etc.

Nuclear energy store - the energy stored in the nucleus of an atom

E.g.: Uranium nuclear power, nuclear reactors

Types of energy transfer ⚡🔀 - Physics

You can read more about energy stores in my previous post - Energy Stores ⚡🏪 - Physics! 😊

What is energy transfer?

When we talk about energy transfer, we talk about energy from one energy store being transferred to another

Energy can remain in the same store for millions of years or just a fraction of a second

There are energy transfers happening all the time - every time there is a change is a system (an object/group of objects), there is a change in the way energy is stored

Transferring energy

There are four types of energy transfer:

Mechanical work 🦾 - the energy transfer of a force moving an object through a distance

Electrical work ⚡- energy transferred by charges moving due to a potential difference

Heating 🔥 - thermal energy transferred from a hotter 🔥region to a cooler 🧊 region

Radiation - energy transferred via waves (e.g.: sound 🔊 waves, light 💡radiation, infrared (heat) radiation)

Example of energy transfer: A falling ball

You are holding a metal ball that doesn't bounce. You drop it...

While the ball is falling:

The gravitational potential energy of the ball decreases 📉 AS

The kinetic energy of the ball increases 📈

As the ball is falling, some energy is transferred to the thermal energy of the surroundings (air)

When the ball hits the ground:

The gravitational potential energy of the ball hits zero AND

The kinetic energy of the ball hits zero AS

Energy is transferred to the surroundings via sound waves (there's a noise when the ball hits the ground) and heat (thermal energy store of surroundings 📈)

The Perseus Constellation

Post #17 in Physics and Astronomy, 03/02/2024

Welcome back,

In spirit of the Percy Jackson series’ first season coming to an end, I figured it was time to share some knowledge about a very famous constellation that you may or may not have heard of, named the Perseus constellation. 

First, it may be appropriate to explain the story of Perseus, the mythical hero. I say this because a lot of the foundations of mathematics and metaphysics come from the work of Greek mathematicians and philosophers, so to explain some of his story is the least I can do to give it some justice.

Perseus, the Greek hero

The King Acrisius of Argos, disappointed in the fact that he didn’t have a son, consulted the Oracle at Delphi. He was warned that he’d be killed by his own grandson, and in fear of his own life, he imprisoned his only daughter, Danaë, in the courtyard of his palace. Despite this, she found herself with child eventually, as a result of Zeus himself falling in love with her. Deciding to visit her in the form of golden rain, she fell pregnant, eventually birthing a baby boy whom she named Perseus.

His most famous story, perhaps, may be the fact he was the one to slay Medusa. Polydectes, the ruler of the island of Seriphos, came to fall in love with Danaë. Perseus deemed him unfit for his mother, and, angry, Polydectes schemed to have Perseus sent away. In short, Perseus didn’t bring the correct gift to a large banquet held by Polydectes, so the former asked him to name any gift, and he’d bring it. The gift named was no other than the head of Medusa.

With the help of Zeus, Hermes, and Athena following a prayer to the gods (or the Hesperides in other versions), he was gifted with various items to help in his quest, like a pair of winged sandals, Hades’ helm of darkness, and Athena’s polished shield. With Athena’s guidance, Perseus was able to slay Medusa and take her head with him in a knapsack.

The final detail in Perseus’ story I find worthy of mention is his marriage. 

Queen Cassiopeia of Aethiopia had once boasted that her daughter, Andromeda, was more beautiful than the Nereids (sea nymphs). This drew the vengeance of Poseidon, who set a upon the land a sea serpent.

Andromeda was tied to a rock on the shore, but Perseus was quick to come along and slay Cetus, the serpent, using the harp given to him by Hermes. Perseus and Andromeda were married soon after, and following her death, Athena hung her among the Perseus and Cassiopeia constellations in the sky.

How romantic.

Perseus’ location, surroundings, and features

Of all the constellations in the sky, Perseus is the 24th largest, occupying an area of approximately 615 square degrees. It’s within the first quadrant of the northern hemisphere, and its neighbouring constellations are Andromeda, as aforementioned, Aries, Cassiopeia, Taurus, and Triangulum. 

There are also two meteor showers associated with Perseus, the Perseids (which should be visible in July-August of this year), and the September Perseids. 

The International Astronomical Union approved of eight names for eight stars within the constellation. They are: Algol, Atik, Berehinya, Menkib, Miram, Mirfak, Misam, and Muspelheim. 

Finding Perseus

Here’s the image from earlier again. Though you may only be seeing a cluster of stars at first, you’ll quickly realise there are some distinct shapes within this, shapes you’ll recognise across all images of the constellation. This image is a ground image found on the Hubble website.

Most notably within the constellation is the shape of a tilted stickman poised to strike, at least that’s how I’m seeing it. 

You can find the full-size image here—it’s beautiful, I couldn’t show it here, since the file size is too large.

have to do a triple chem paper tomorrow and can i just say that paper 2 is a godsend compared to paper 1. fractional distillation? reversible reactions?? freaking potable water? i think i might be in love.

#the topics may be dull #but my god are they easy #organic chemistry #rate of reactions #atmosphere #chemistry #i barely need to revise #physics is gonna suck #but that's future me's problem #so excited for the actual mocks #(/lyiNG) #chemistry student #chemistry studyblr #gcse student #gcse studyblr #studyblr #gcse 2024 #HHjhjkhHKghFFGdgf #mmkay monomers can go die in a hole #but c9 is beautiful

love people posting close ups of the cars and being like HMM 🤨🤨 we’re cooking? we’re doomed? like absolutely hun it all looks the same to me but love you nerds 🫡

#couldn’t tell ya if you’re posting a wing or a tyre but great! #keep telling me what to think and like a sheep i will baa #the streets will remember i got 98/100 on my physics gcse tho

[scribbling-dragon]

Juno, respectfully, what the fuck is up with your bio teacher

to be completely honest with you i don't actually know hdsjhjkd

sometimes he can almost pass as a relatively normal science teacher but then he just does SOMETHING that reminds you of why he's the little freak of the science department (affectionate)

i do love having him though hjdshjk he bought all of us hot chocolates from the upper school cafe for christmas. he also chats w one of the people in my class about the witcher. and puts minecraft music on to help us relax (he has a gamer chair. he showed us photos of it bc he was so happy when he got it)

#we're having tours from primary schools rn that are tryna get the y6s to come to my school next year #and a buncha teachers are doin tours for it. and when he was asked why he wasnt he said that he was told he was “responsible enough” to do #-tour #i mean. there's also my gcse physics teacher..who was definitely wild as hell. and didnt actually teach us? (still got that A* tho) #and my y7 comp science teacher! he got fired for comin into school high #yk what. maybe its just a my school problem #asks #anon

[bookobsessedblob]

why is aqa still giving out the wrong advanced information when they’re literally the biggest exam board in the uk 

#do better #seriously it’s not that hard to give correct information to students so that they don’t mess up their entire futures?! #gcse physics #a level law #gcses 2022 #a levels 2022

GCSEs will genuinely be the death of me. If I get good results(AMEN GUYS AMEN) I'll update here, and celebrate like its the only happy moment in my gloomy life (partially true) and if I disappear from the face of the Earth for a few weeks(or months) even after Rafa's return at Doha.

Then yall know what's up😔😔

#gcse #pray for me guys i need to collect as much luck and prayers as possible #THIS WILL LITERALLY DETERMINE MY WHOLE LIFE #if i fail this then what am i even going to do with my life #I HAVENT EVEN THOUGHT ABOUT IT BYE #qas' shitpost #bye im going to contemplate my life choices #and prepare a speech for my parents on why i got. what i got. #IM SCARED I HAVE STOMACH ACHES RN #i feel physically sick #gcse student
