Work Definition & Equation & Problem Solution Calculation in Physics
Переглядів 4953 роки тому
Here is the definition for work and how to calculate work in Fzx class. A few examples are included. Circular satellite motion is an example of zero work being done by the gravitational force since thee displacement is perpendicular to it.

Fzx Wrdz - English Spelling Lesson in Physics Class
Переглядів 2023 роки тому
"PHYSICS" is one of the worst offenders of English spelling "rules." Here we consider some of the better spelling options for Fzx wrdz we commonly use.
ADVANCED TERMS - speed/velocity distance/displacement acceleration
Переглядів 2873 роки тому
Terms in Physics are essential. This is the ADVANCED version where we DO differentiate between distance/displacement and we use uplevel definitions of speed/velocity. Memorize and practice these terms or you'll have serious problems with Physics in the future. Speed and velocity and acceleration are all different from our normal use of the words. Thanks for Liking and Sharing. New videos most w...
BASIC TERMS - speed/velocity acceleration vector/scalar mass/weight average/instantaneous
Переглядів 4723 роки тому
Terms in Physics are essential. This video is the BASIC version where we do NOT differentiate between distance/displacement and where velocity is simply speed with direction - the rest is the same. If you don't memorize these terms you'll have serious problems with Physics in the future. Speed and velocity and acceleration are all different from our normal use of the words. Memorize and use the...

This is a mass/weight relationship lab for 100% virtual learning since I couldn’t find a good virtual lab already out there with the details I need. Click the circle-i for attached videos and playlists. There’s background and graphing and conclusion information available. Complete topical playlist: t.ly/Tvs2
Electrostatics Introduction - it’s the ELECTRONS!!
Переглядів 3104 роки тому
Electrons are the key to a good understanding of static electricity. First Quarantine Lesson of 2020!! We must remember that everything is made of ATOMS and that atoms are mostly NOTHING and that atoms get their structure from ELECTRONS that are on the OUTSIDE. Adding electrons makes something more negative. Removing electrons makes something more positive.

As a 12 year old this video is very helpful I’m playing a game called scrap mechanic and making a piston engine and wanted to learn about gears to help thanks
This was fantastic, but what I really need most is a practical guide to incorporating geears into designs for makers. Common ways to arrange drive shafts and how to pick the best gears to simplify designs and minimize friction. How to decide how many teeth you should have etc. There is so much to know and I don't know where to look!
Bro got veins 🗿
Voltage is emf
Nope
Thank you! I'm 30 years old and finally getting this idea into my head <3
Took me a while too!
helped a lot thank u

The best teacher ever
Thanks
“You just learned physics”, brilliant. I love how simply you broke everything down. They say it takes a genius to explain something complicated in a simple way, so I’m nominating you for genius of the year my friend! 💡
Thanks! Feynman taught me well!
ტჰის ის ვერი გოოდ0;0:):
I have no word for u that how much u have hepled me
Just what I needed for my Physics Exam
Finally a physics teacher that says this, thank you! Do you know any physics society or article about the dumbness of that unit. Im also a physics undergraduate and I think physicists should change their habits about that.
Is it the Mack granite?
Could you please provide the model number on this toy? It’s too expensive to order the wrong one and many similar looking models
Literally the video i was looking for ☺️
Continue
Continue please
Remarkably short, yet I still understand perfectly. Thanks.
Central force is assembly line perfection
Cosequance
Excellent explanation in its simplicity.
thanks a lot !!!! i understood it finally !!!
i didnt understand shit
Thanks a million 😌
Best physics teacher I had 505k views
These are kinda fun to use.
U motherf*cker.....how to know clockwise and clockwise by seeing the sign of (r X. F )....that was query and u r fooling us with a pen .....what have u done is already experimented by all your viewers
Thank you so much sir!!
Excellent! This should have a million view cuz this is so good!
how do you determine the direction if the force is at an angle ?
It really is the best toy ever! 😅
good video👍
Exelen!!!
Tailler des engrenages en bois
Vertical angles
How much is it?
But what about torque moments (so when you would actually apply a moment on the longitudinal axis, ie spin your pen) what is the sign convention for these?
thanks for the vid. very informative.
I don't think you mentioned what "IMA" means. Is that "Inherent Mechanical Advantage"? Would be simpler to just use MA. Good video. I'm sharing it.
Thank you so much it really helped 🙌😭
I set up two wheels as in ‘wheel and axle lrn fzx’ right by each other. I used the wheels as Atwood’s with the same extra 20 g mass added at the 35 mm dia. One of these two Atwood’s machines accelerated 120 g at the 35 mm diameter and the other accelerated 40 g at 105 mm diameter. The 120 g was a string with 60 g on each side and the 40 g was a string with 20 g on each side. The strings were draped over their appropriate diameter of the pulley. I ran the two Atwood’s at the same time and they accelerated at the same rate. That means that the 40 g was accelerated to three times the velocity as the 120 g by the same input energy.
I have one
In fact you are not measuring current you are measuring microvolts with a microvolt meter current is not real and it doesn't move electrons is like a resistor divider in series so is a voltmeter and not an Amperemeter
Is there a name for this experiment? cause i´ve made an animation about this experiment and i´m not sure how to name it
Цікаво
Thanks
Good day im a highschool teacher can i ask to use your video for educational purpose thank you'
