I'm a physicist, a dad, and a teacher. You can learn more about me by visiting my website www.physicsninja.org.
I tutor math and physics online to students across the US and Canada and I try to help them become better problem solvers. Feel free to contact me if you have any suggestions for a video. I'd love to help you understand something better.
I work full time as an engineer in mobile consumer electronics and i'm also an adjunct physics instructor at Harper College and Elgin Community College.

Love from INDIA 🇮🇳❤❤❤ SUPERB
На харчову нержавіючу сталь магніти не впливають!
Centripetal force or centrifugal force?
What are those dang meddling kids up to in the background audio!?
Superb explanation.. And thanks to answers sir
Thank you
In indian these problems were taught in 11 th standard And much more tougher these came in JEE advance

Seems Legit.
It’s centrifugal force! Dummy.
As some physicists correctly refer to it, it's tangent force
Gravity and magnetism are true (and mutual/dynamic) centripetal effects or forces, whereas all other forms of circular motion in physics are from non-mutual factors acting against straight line movement or gravitational trajectories.
tangent
Angular momentum.
it’s as simple as Hey, diddle, diddle! The cat and the fiddle, The cow jumped over the moon; The little dog laughed To see such sport, And the dish ran away with the spoon.
Excelent . Thanks a lot. Like and suscribed.😊
Well deserved, you helped me pass, my first semster on physics when I thought there's no more hope coz I failed the first test very badly but anyways I😂Killed the rest of the tests and exams thanks to you❤🎉
Banger of a video. :) keep up the good work.
Why does it happen? Can you make a detailed video about angular momentum and precession.
I mean it shouldnt take too long to explain. The air pushes on the back part of the disc, but the disc is spinning in the process, so while it is going down, that part is also going to our (the viewer's) left
The next thing you'll be trying to shoot a rocket to outer space
Ох уж эти токи Фуко 😂
These Spaghetti Forks, Mixing Stick and Spatulas are now Perfectly👌 balanced for the kitchen👨🍳
thank you Mr it was helpfull
How do we get the law V=k.. Q/r from this law V=k.E/Q
Battery?
Thanks!!
I Was Thinking Copper. Never thought of Aluminum. Try Dropping a Magnet thtough a Copper Pipe. It Slows to a Crawl. Interesting in the Fact they are Non Ferrous(Magnetic), Paramagnetic. Strange Copper and Magnets can Make Electricity.
Horrifying. I don't think I will sleep tonight.
This explains nothing.
I’d be willing to bet the comb shaped one would like light a led or have some effect below the pendulum from alternating currents sent down the “comb teeth”
Truly the best explanation.
Logisch... 😂
Different fabric, plastic vs cooper :-) And magnet.
how
Thank you so much!

Charge time delay...😢😢😢😅

For some reason, this brute-force derivation always makes my head spin a little, and I've tried to think of it in a way that makes conceptual sense. See what you think of this: The future value (to the bank) of the principal P at maturity is P(1+r)^n. The future value (to the bank) at maturity of the first payment M is M(1+r)^(n-1) because the bank will have that money to loan out for n-1 months. Future value of second payment is M(1+r)^(n-2), and so on until the last payment is worth M when paid at maturity. Since the payments satisfy the loan, you get P(1+r)^n = M(1 + (1+r) + ... + (1+r)^(n-1)). Add the geometric series on the right and get the result.
Excellent teaching tools 👍✌️
But for a conductor the electric field inside is zero and therefore in the case 2 the charge is zero
Or the inside is dielectric?
Какие-то неправильные расчёски 😅
Now lick it.
Los imanes y su campo magnético producen en los conductores cerrados, una corriente inducida que a su vez crean un campo magnético en la misma dirección y sentido al campo de los imanes. En el primer caso, al no existir un circuito cerrado, ya que el peine no cierra sus puas por abajo, la corriente inducida sería casi nula (recorrido muy largo y difícil -> mayor resistencia eléctrica). En el segundo caso, aunque induciremos corriente y generaremos un campo magnético que hace que sus lineas de fuerza creen un iman inaginaro, orientado con los polos para ser atraído por los imanes reales , estará limitado al paso de corriente por los peines, que tienen resistencia. En el ultimo caso al no haber restricciones, la corriente inducida será máxima y la frenada causada por el campo inducido también. Inportante: Para que se produzca corriente inducida en un conductor cerrado, tiene que haber una variación de flujo de las lineas de fuerza del campo magnetico inductor. Es por ello que los transformadores son de corriente alterna o variable.
