Science notes

RadMaths home page $\text{Note created on 2021.5.4, Tuesday}$ Here I will be posting a course on science. The whole thing should be ready in a year or so :)
All content is handwrited :) feel free to comment below if you find any problems :)

Sorry that the pics are small :/ I can’t modify them :/ just adjust the size of your browser :)

Easy Math Editor

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

i was acutually just about to mention you dude! cuz i prepare to write something about simple machines(springs, pulleys) later on, and i couldn't list them all out! could u help me?
thanks in advance :)

Of course I would love to^_^ ,why are u even asking ʕ º ᴥ ºʔ

@Agent T – A teeny weeny bit on springs that I just remembered

All springs work because of restoring forces acting on them that tend to restore the spring's configuration.
The restoring force is directly proportional to the displacement of the spring from its mean/equilibrium position (larger the force,larger the displacement).
They somewhat are related to waves (spoiler alert) but that's a really interesting topic and I don't wanna spoil the fun and will be talking about it in detail later :).

@Agent T – thanks! what other kind of machines are there ? (im going to write this out so im paranoid of missing anything) you dont have to explain to much :) just listing them out would be ok :)

@Jeff Giff – Ohh okay!

Pendulums,trolleys,wheels on an inclined surface(rolling/sliding),Guns, airplanes,collisions of object with varying masses,lifts/elevators,ships/sailing vessels,etc

@Agent T – I mean those simple ones I can explain in physics so yeah, that’s enough :)

How many pics can you see now? I uploaded six, but I can only see four!
