அனைவருக்குமான இயற்பியல் இயக்கம், வெப்பம் (Physics For Everyone Motion, Heat In Tamil ) by எல். லாண்டாவோ (L. Landau); அ. கிட்டகரோட்ஸ்கி (A. Kitaigorodsky)
We have tried to write this book in a light and simple style, not denying ourselves the pleasure of an occasional joke with the reader. But this does not in any way mean that our Physics for Everyone is an easy book. Many of its pages must be read attentively for a long time; in order to understand physics, one must very often think hard and tensely.
The book’s main concern is the fundamental laws and concepts of physics. However, we have tried not to forget about illustrations from life and technology, true, not having the aim of dealing in any way with the inexhaustible field of applied physics.
நாங்கள் இந்தப் புத்தகத்தை இலகுவான மற்றும் எளிய பாணியில் எழுத முயன்றுள்ளோம், வாசகருடன் பொழுதுபோக்கு செய்யும் occasional ஜோக்குகளை நாங்கள் தவறவில்லை. ஆனால் இது எங்கள் ‘எல்லோருக்கும் புவியியல்’ ஒரு எளிய புத்தகம் என்பதை பொருளல்ல. அதன் பல பக்கங்களை கவனமாகவும் நீண்ட நேரம் வாசிக்க வேண்டும்; புவியியலைப் புரிந்துகொள்ள, பல முறை தீவிரமாகவும் சிந்திக்க வேண்டும்.
இந்த புத்தகத்தின் முதன்மை கவனம் புவியியலின் அடிப்படை விதிமுறைகள் மற்றும் கருத்துக்களிலேயே உள்ளது. அதே நேரத்தில், வாழ்க்கையிலிருந்து மற்றும் தொழில்நுட்பத்திலிருந்து எடுத்துக்காட்டுகளை மறக்காமல் இருக்க நாம் முயற்சித்துள்ளோம், ஆனால் வரையறுக்க முடியாத ஆபரேஷனல் புவியியல் பற்றிய விரிவான விவாதத்தை எங்களது நோக்கமாக வைத்திருக்கவில்லை.

Alright, future engineers!
**Impulse:** The change in an object's momentum, or force applied over time.
Ex: `Impulse = F_avg * dt`. Catching a ball softly increases `dt`, reducing `F_avg`.
Pro-Tip: Great for collision analysis—it links force, time, & momentum change!
#Mechanics #Collisions #STEM #StudyNotes -
Alright, future engineers!
**Impulse (J):** Change in an object's momentum.
Ex: `J = F_avg * delta_t`. A car crash reduces force with longer impact time (airbag!).
Pro-Tip: Same momentum change, but longer time means less average force! Think safety.

If you have an early 2000's RAM, and the transmission throws a code 4, if they have to replace the solenoid pack, also have them check the transmission cape connector. The cape connector can start shorting out, and most shops don't check it when swapping out the transmission solenoid pack.
The shorts from the cape connector will randomly knock out the transmission solenoid pack, and other important components of the truck.

**Newton's 1st Law (Inertia):** An object's velocity won't change unless a net force acts on it.
Ex: A space probe coasts at constant velocity because no friction or air drag.
Pro-Tip: Mass is the measure of inertia! More mass = harder to change its motion. -

**Work:** Energy transferred by a force causing displacement.
Ex: Lifting a `10N` weight `2m` up means `W = 10N * 2m = 20J`.
Pro-Tip: Only the force component *parallel* to motion does work! Perpendicular force does *zero* work.

**Momentum (p):** A measure of an object's mass in motion.
Ex: `p = m * v` (mass times velocity).
Pro-Tip: In isolated systems, total momentum is *conserved* (constant)! Essential for analyzing collisions & impulses.

**Newton's 2nd Law:** Net force equals mass times acceleration. It governs how forces cause motion.
Ex: `F_net = m * a`

I wish I understood #cars and #computers (repeat rant), because if I understood them then I could #fix them, and not be #dependent on men #mechanics who realize I’m an #idiot (with respect to the machine) and I will put anything on my #creditcard because IDK what else to do.

Finite Element Analysis rabbit hole.
#PrePoMax works passably on Linux and with youtube tutorials (thanks Indian- and Polish-accent guys) I could actually simulate twisting a rod and do experiments. Easy to use for a total newb!
That informs me where to place strain gauges for one of my projects.
I promise all the random stuff I've been doing ties together, eventually.
