# 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 fin any problems :)

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.

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?

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

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 :).

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 :)

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
