Your 6 min videos help me learn more than I do in an hour of class
True
IKR
+Nico's Rap Holy shit.... ikr these teachers are soo bad.. i have a chinese teacher that bullies me and picks on me... in so meny ways... ;'( i cant handle it anymore.
Kevin Oliver Haha, I took Chinese in middle school and the teacher wasn't the best either. 😂😂
she is so mean to me you have no idea... she is also wrong in almost everything... So there is 2 teacher. the main "smart teacher"then there is the co ed teacher " mean china women who thinks she knows it all".... So i asked the main teaher to fix my work and she did.. and the china teacher said the the fixed work of the main teacher was wrong and she told me i had to re do the entire thing.... BUT THE CHINA TEACHER WAS WRONG BC I WENT TO THE MAIN TEACHER AND TOLD HER.
I swear i learn more from CZcams videos than I do my teacher. Why waste an hour and a half in class when i can spend 6 minutes watching a video.
I learn from freind teachers and youtube.
You my friend. actually make sense. something my science teacher lacks
lastminutestudysquad where you at?
here :)
Here
here
Howdy
Oh no am here ain't I
Thank you for your simple explanation, and not talking really fast- like a lot of people on Utube
Thank, Mr. Andersen. That is a great explanation!
Excellent work. Thanks from a fellow science teacher.
Did this is class for 2 hours -.- did not understand a bit, watched this for 6 min, understood everything
to convert mph to m/s, just multiply your speed by 1609 (how many meters in a mile) then divide that by 3600 (how many seconds in an hour)
this makes it (speed x meters)/(seconds), hence the notation, meters/second
Thanks haha
Thanks I was kinda confused with thatt.
This is very helpful! Even though I'm in 6th grade, this is very interesting and good help for my test!
you in grade nine now?
how you learning this in sixth grade bruh im in 8th grade just learning this
with this video, I was able to calculate that a modified lake tahoe (lake height + 50M) and clearlake region (dammed up to 550M elevation) could power the USA's current energy needs for 7 days if converted to pumped ocean storage at 50% and 70% system efficiencies respectively.
That's the time frame for which a UCSD physics professor claims that we'd not need to tap any other power source to power our country. pumping would be handled by renewables, connected, presumably, by a high voltage DC underground grid due to 2x efficiency of current high voltage AC overhead line theoretical maximum efficiency.
Mr. anderson isn't the gravitational acceleration positive 9.8 m/s ??
Or am i getting something wrong here?
Mahima Kochar m/s are the units for velocity. You are right that gravitational acceleration is usually about 9.8m/s^2(it varies slightly with altitude). Some people put it as positive, others negative. Either way is fine as long as the sign remains the same with in a problem.
For an example if you decide the downward direction is negative your gravitational acceleration will always be negative, and the same goes for positive.
Hope this helped:)
The +/- direction thing confused me at first, just remember that the sign is just a symbol. You can decide away from the earth(up) is negative, and down is positive and vice versa.
It's not 9.8|m|s^2, it's 9.81m/s^2.
Love your video ......please upload moor soon
Thanks a lot sir!
what the actual fck? i learn so much in this 6 min vid than my 40 min class?
Interesting to the core. What if kentic energy is useful to evolve our automobiles. I don't mean to measure the energy it is traveling in, I mean energy that can be given to a automobile to set a significant forward motion. What if science can take a foot long object (strip like ) that can create potential energy and set it down on a pavement. Then take a second strip set it a foot apart and so forth for a distance of half a mile. Take a vehicle light enough and suitable to begin at one point,the first strip. And allow the first strip to generate the energy to push the vehicle forward to the next strip and then that strip to the next and so forth for that half mile distance. It could be used on our freeways and main roads. It could a beginning to revolutionizing our autos and calming its toxic waste.
rapprelevant3313 that's nosense ke is something and using other smart source of energy is another thing
Clear, simple, concise and to the point....very well explained and informative. Thank you
Thank you. I have learnt more from watching youtube clips on physics that I have with our uni professor :(
I understood in 6 minutes what my physics teacher failed to teach me in 45 minutes.
Thanks man u cleared my ask concepts
Thanks very much! A great and helpful video!
this is pretty good, dude/
Got my AS Level Physics exam tomorrow morning, this helped a lot, thank you!
both serios and not.
Awesome video, thank you so much!
Hey I just wanted to thank you for your great videos. I skipped Physics 1 and went straight to AP Physics C and you've helped me cover everything I missed.
Thank you!
very well explained man
physics exam tomorrow & chemistry exam on friday..
your videos helped me more in a day than my teacher did in a year..
THANK YOU SO MUCH.
tnxxx for your video clip about this topic,,,i really understand the difference between kinetic and potential energy,,,,,you are so bless of mine....and tnxxx also to this website youtube its really really helpful.....
this is so awesome !! thanks a lot
You got good stuff going here, keep it up man!
Just one thing: The physics course am doing, in England OCR, the formula that you used for p.e is what we use for GRAVITATIONAL p.e, but with your explanation and worked example this seems fine.
thanks my assignment is done yay
Thank you so much man, My freaking Vietnamese physics teacher such a bitch that doesn't even know how to teach, It help me a lot!!
good stuff sir.
Thank you SO MUCH
HOw do i figure out the minimum kinetic energy
Excellent Video
Thank you bro☺
Fantastic, fantastic, fantastic!! Clear and well thought out. Thanks a lot
I feel so dumb I still don't understand and I have a test tomorrow :(
Ilona Masimova your just stupid then
Blaze 1134 *You're. Who's the stupid one now? haha
Ya u r dumb
Mood
me toooo :(
I dont know sht about this but this video helped thanks
other sciences are fun,space and earth science.
thanks!
Thanks for sharing!! Can you do a pole vaulting problem with PE and KE?
So would another good example of potential energy be a sprinter in starting position? Then as he starts sprinting, all that potential energy converts into kinetic energy, right?
excellent concept
great video, thanks. so easy
What does a light wave look like, with all kinetic energy and no potential energy?
I know that work=force×displacement
Its not work = force×distance
Great video
at 5:10 Getting half of .145 kg is .0725. 45 multiplied by itself is 2025. Multiplying 0.0725 to 2025 will be 146.81. How did it end up to 150? What did I miss?
Great Comparison, I teach ballet. I'm NOT a physicist, but I do need help, I have the students do beats with their legs closing front and back very very fast. I tell them they need to use the kinetic energy produced when they hit their thighs together they create the energy to rebound. Question, is this Kinetic or Momentum shift?
THANKS ALOT !!!! saved my time of studying over 50 pages :D !
❤️your videos.. you are awesome!
Thank you🙏
I have a quiz tomorrow on this and I forgot my book in school, this helped me so much, THANK YOU!
acceleration due to gravity we can use 10 m/s square
+manoj dookarun No, it's 9,81 m/s^2.
ok Thank you sir
+trhj45uotsryegf4y5rstg We have tu use 9.813 m/s^2
does anyone know if you have to us significant digits
Thank you! I wish you were my college professor
Thank you very much :)
your 6 min video really helped me bc even though i listen in class and stuff when it comes to homework i usually use youtube to find easy and simple tutorials that will help me as I'm in year 9 and we are doing hard?easy stuff but yeah :))
Energy divided by time is the power
Oh yeah yeah
Very Helpful
Plz teacher, can you tell me where you get 9.0m|s
man this saved me
sure
thank you
maybe im multiplying wrong but i get 2397 joules for potential energy. how did you get 24485.16?
really thank you i did very well on my science test and u helped me a lot good man keep up the greeeeat work
you said -9.81m/s2, but the problem says 9.81m/s2 so wouldn't the answer be -24485.76 joules. im confused by what you said, is it a -9.81?
Sarah Rivera It's negative because gravity accelerates towards the Earth, but if we are doing these problems, it's only natural to understand that you can't really have negative potential energy, you wouldn't be able to do a thing.
Is there a hyper thetical version one for if the ball Straight down then hits left creating motion change the motion of the mass keeping momentum and then keeping it there by manipulation of the field.
Using gravity to keep something (mass) moving generating motion (kinetic) changing the flow in a ball like stucture (magnetism) of the field (gravity) to keep the flow. moving.
1 South + 1 West = 1 North continuous loop generated like muscle refex moving continues slows down by issue of friction unless the friction gets manipulated so that it moves continues.
How to solve the acceleration of potential energy by time?
I can't remember why 11.3m/s is important. I read it somewhere in a physics book but can't remember what it was referring to. Would you have any idea why it is important?
escape velocity!
So potential energy is the object at rest and kinetic energy is the object in motion? (:
What mistake am i making on the equation for potential energy i do 78*9.8*32 and end up getting 2.4460.8?
I loved it, that was very helpfull. Physic is more of a concept, If you don't get the concept, basically you are gambling in solving a problem!
Isn't the acceleration of gravity is 9.8m/s? or 9.81m/s?
9.8m/s/s
Daniel McLay More like 9.81 m/s^2
the exponent over the unit "s" is important
eugine's original comment just said m/s
Depends how specific it wants it. Some problems it want u to use 9.81 and others 9.8
Very helpful thanks ..
If it's sliding is it potential or kinetic energy
my science teacher are science teacher write down under notes that how to do Connecticut and she and how to solve it any ideas put .5 times .03 kilograms times 400 meters per second squared and your video you did not put the .5 EE before your thing and so I'm trying to do my homework now really know how to do it so I was looking on CZcams and I I keep getting it wrong and I I don't know what I'm doing wrong but should I take out the .5 or what?
Thank you so much! This has made my science exam tomorrow not so scary! :)
Great , but how the potential energy is related to the work
So energy is not something tangible, but rather just a measurement?
May I ask how is squaring 9 get 5.9. It's suppose to get bigger?
He multiplied half of .145 by 9^9.This would make 81 much smaller.
Great!
love you for this, now i understand everything
love it
I thought the voice used here was from the text-to-speech meme xd
Also, I got it now! :D Thank you!
This is helpful for the basics but not very helpful for the harder problems I am currently stumped on

Thank you sir that really helped me understand the concepts! It was really clear and well explained :)
how did you get the 10⁴ joules?
I got confused
thank you
Loved it
Thanks,don't know how i didn't see that :)
Thx a lot ur a genius
There is no kinetic energy in a moving mass there is force Mv squared kinetic energy is the energy of consistent work from a consistent force regards Graham Flowers
when you made that "cilcles" that mean the mass i guess i just thought something like AMATERASAU
Bruh 🤣🤣
Thanks for this sir! Not really for a subject just some self improvement. QUESTION: When I solved the 100 mph the result was, 146.8125 so, even with round up it should be 147, right? Which is contrary to yours. Why is that? I appreciate your help and attention. Thank you again!
im doing homework by watching youtube
how did u get the 45 meters of weight?
he converted mph to m/s
Potential energy depends upon height so how can the pendulum u holding has some potential energy
Depends on distance from location.
Gravity will pull it down but the string will keep it in a semi-orbit.
Really helped
Looks like Khan Academy has a competition.
what if a rod made of tungsten 6 meters long and .3 meters wide fell to earth at mach 10, what would be the area of impact?. i say this because i watched an interesting video about the cold war and well... you can probably guess what it was used for :D.
