Inertia - Basic Introduction, Torque, Angular Acceleration, Newton's Second Law, Rotational Motion

Thank you so much tangina!

I am 60 years old. Have two science degrees and still have difficulty grasping the moment of inertia. First off. There is no moment. It is a measure. So why is it not called the measure of inertia?

Man i hate Physics so much

Objic

Why doesn't the thickness of the thin hoop change the inertia? If you think about it, if the thickness of the hoop was .99999R compared to the solid disk, the formulas will state that the inertia of the hoop is twice that of the disk, which doesn't really make sense since they're very similar to each other. The only difference is that the hoop has a very small hole at the center.

The last minete dont undestand😕

Which of the two will accelerate faster?
T = I x alpha
For solid disk
I is smaller than hoop
Means lower resistance to motion than hoop
So
Solid disk will roll down faster

What moshen? Poop?

This is really helpful! Thank you so much for your help!

best channel. thank you!!!!

This the best definition and understanding of the concept. I’ve watched almost 5 videos this one is the best !

This guy is a legend

I really wonder why I decided to take physics as an elective

im in love with you

Thanks

lahian mo kohhh

Next level bro... awesome explain nation

love u

Thanks this was really helpfull

Continue to teach us thanks 🙏

The only way to pass exams🙌

You’re a life saver

how can i calculate the inertia of a polygon?

Man, clear as day. When you can grasp the concept, the rest of the lesson becomes a satisfying curiosity. Thanks a lot.

Thanks! 🧡🧡

If it helps anyone for physics 1, Always think of things in terms of direction
- think of all 4 directions for every problem
-choose what direction you want as positive
-Keep basic ideas committed to memory like Momentum conservation, kinetic energy, potential energy etc, simply conservation formulas is more than enough dont overthink it
-learn what a derivative and integral really is, this will help you understand whats really happening and youll tie things together more deeply.
-remember that trigonometry can be used too, its a tool not baggage

and definitely learn to derive the 4 basic kinematic equations that is the quickest way to learning linear motion.

TIME is NECESSARILY (AND CLEARLY) possible/potential AND actual ON/IN BALANCE. BALANCED inertia/INERTIAL RESISTANCE is fundamental. Carefully consider what is THE EARTH/ground. It is the experience of WHAT IS FULL GRAVITY ON BALANCE. Carefully consider what is THE EYE ON BALANCE. E=mc2 IS F=ma. Consider TIME (AND time dilation) ON BALANCE. The stars AND PLANETS are POINTS in the night sky ON BALANCE.

Is the 1/2 an approximation? Wouldn't the fraction depend on the relative thickness of the disk?

so bike tires with spokes are harder to rotate than a solid wheel if the mass & radius are the same?

THANK YOU SO MUCH GOD BLESS YOU 🤍

I am studying in Turkey and I am in 11th grade. We learn about this in physics. This video helped me a lot in my exam. Thank you very much.

😶

thanks!

PLEASE call it "ROTATIONAL INERTIA" or "MOMENT OF INERTIA" or "MASS MOMENT OF INERTIA" and not "Inertia". Inertia of both the objects is same because they have same mass and will posses the same tendency to resist any change in their state of motion and cannot be calculated using a formula.

Fantastic explanation of Inertia. I have been struggling with this concept until I found your concise video. Thank you!

ty... a lot

I love your videos. Learning a LOT. You skipped over something though…. which I am struggling with…. M=I…. how did alpha end up r(squared?) I am not the smartest, nor the dumbest…. this was not clear.

this is a crazy good video to draw connections between translational and rotational motion

The ultimate unification and understanding of physics/physical experience combines, BALANCES, AND INCLUDES opposites, AS E=MC2 is CLEARLY manifest as F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. Here's the proof. This also explains why objects (including WHAT IS THE FALLING MAN) fall at the SAME RATE (neglecting air resistance, of course), AS E=MC2 IS CLEARLY F=MA ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. TIME dilation ULTIMATELY proves (ON BALANCE) that E=MC2 IS clearly and necessarily F=ma ON BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity is ELECTROMAGNETISM/energy ON BALANCE.


ON THE CLEAR, EXTENSIVE, SENSIBLE, BALANCED, THEORETICAL, AND UNIVERSAL PROOF THAT ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS clearly PROVEN TO BE F=MA ON BALANCE:


Balanced inertia/INERTIAL RESISTANCE is fundamental, as ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE; AS gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY proven to be F=ma ON BALANCE. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Indeed, A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course); AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS ELECTROMAGNETISM/energy is gravity ON BALANCE; AS E=MC2 is CLEARLY F=ma IN BALANCE !!! Gravity is ELECTROMAGNETISM/energy ON BALANCE, AS E=MC2 is CLEARLY proven to be F=ma IN BALANCE. TIME dilation ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS the stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 is CLEARLY F=ma ON BALANCE. The stars AND PLANETS are POINTS in the night sky. Accordingly, ON BALANCE, it makes perfect sense that THE PLANETS (including WHAT IS THE EARTH) will move away very, very, very slightly in relation to what is THE SUN !!! ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma ON BALANCE. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/ENERGY, as this balances gravity AND inertia; AS E=MC2 is CLEARLY F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. GREAT. I have explained the cosmological redshift AND the supergiant stars. Stellar clustering ALSO proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 is CLEARLY F=ma IN BALANCE !!!

Wow!! is their any way it can be described more.I love it!! Thank you.

Thank you soooooo much!!!!!!

ok i get inertia the first part. but apparently im too stupid to understand the rest :)

i live here now... neva gonna leave.

ON THE ESSENTIAL AND NECESSARY RELATION OF E=MC2 AS F=MA (IN BALANCE), AS ELECTROMAGNETISM/energy is clearly gravity AS WHAT IS NECESSARILY POSSIBLE/POTENTIAL AND ACTUAL IN BALANCE:

Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity ! Gravity is ELECTROMAGNETISM/energy. The stars AND PLANETS are POINTS in the night sky. ACCORDINGLY, the Moon AND THE PLANETS move AWAY very, very, very slightly in comparison to WHAT IS THE SUN !! SO, carefully consider what is THE EYE !! Finally, think about what is the speed of light (c). E=MC2 is CLEARLY F=ma (ON BALANCE), AS ELECTROMAGNETISM/energy is gravity !

Magnificent. It ALL does CLEARLY make perfect sense ON BALANCE !!! This does explain the fourth dimension, including the term c4 therewith !!! "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. (Gravity IS ELECTROMAGNETISM/energy.) Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity ! Accordingly, the rotation of WHAT IS THE MOON matches it's revolution. So, notice that what is THE MOON is basically dead or inert ON BALANCE !!! GREAT. INDEED, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma ON BALANCE !!! The sky is BLUE, AND what is THE EARTH is ALSO BLUE !! (Notice what is THE EYE !!) ELECTROMAGNETISM/energy is gravity. E=MC2 is CLEARLY proven to be F=ma ON BALANCE, AS gravity IS ELECTROMAGNETISM/energy !!! Great.

Carefully consider what is the Sun. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) Consider what is BALANCED observer dependent/related experience ! Carefully consider the man (INCLUDING what is THE EYE) who actually IS in outer "space". NOW, think about TIME; AS the stars AND PLANETS are POINTS in the night sky. INSTANTANEITY is therefore FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience. So, here we have established what can basically and sensibly be understood as constituting a one dimensional relation. A white dwarf star is about the size of the Earth, AND it is ALSO (ON BALANCE) the PROJECTED form or fate (IN TIME) of the Sun !!! Great !!! Stellar clustering ALSO proves (ON BALANCE) that E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. Against what is outer "space", why would the Sun maintain what is its "preferential" existence ? The answer is THE EYE/the observer. INDEED, notice that THE EYE is invisible AND VISIBLE IN BALANCE; AS E=MC2 IS F=ma; AS gravity IS ELECTROMAGNETISM/energy ! Now, ON BALANCE, consider what is the speed of light (c). A galaxy is basically FLAT. SO, think about a TWO dimensional surface OR SPACE (ON BALANCE) as well. HALF of the galaxies are "dead" or inert, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma !! Carefully consider what is THE EYE !!

TIME dilation ULTIMATELY proves (ON BALANCE) that E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Great.

E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM energy.

Excellent !!! BALANCE and completeness go hand in hand !!!

GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Consider WHAT IS THE MAN who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Think about TIME !!! NOW, the stars AND PLANETS do REMAIN AS what are POINTS in the night sky. TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. This explains the cosmological redshift AND the "black holes". Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 is CLEARLY F=ma ON BALANCE, AS ELECTROMAGNETISM/energy is gravity. The fact that the rotation of WHAT IS THE MOON matches it's revolution is not a meaningless coincidence, AS the fact that both the Sun AND the Moon are the SAME SIZE in the sky is not some sort of a meaningless coincidence. Notice the match with the size of what is THE EYE. Magnificent !!! It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. E=MC2 IS CLEARLY F=ma ON BALANCE, AS gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS ELECTROMAGNETISM/energy is gravity ON BALANCE !!! Gravity IS ELECTROMAGNETISM/energy. Great !!! Carefully consider what are the POINTS in the night sky ON BALANCE !!! Think about the necessity (or essential nature) of TIME, AS E=MC2 IS clearly F=ma ON BALANCE !!! Great. It is proven.

("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity. E=MC2 IS F=ma.) Consider what is THE SUN AND what is THE EARTH/ground in DIRECT comparison, AS the stars AND PLANETS are POINTS in the night sky !!!

GREAT !!! E=MC2 IS F=ma !!!!
