Introduction to frames of reference

Introduction to what a reference frame is.

This video explains when Max Planck said "When you change the way you look at things, the things you look at change"

I'm in primary and I remember very well when I was little I used to think about this stuff I never knew the names but now you've helped me understand how to explain this to my friends with the proper names. Thank you soo much!😁😁😁

khan's voice makes me smile and feel safe and happy inside! had to get it out sry :-)

Same things apply to mind. Analyzing an event, you can choose the reference of the cause that you want to start on. If you trow a rock, what’s the cause? Your hand? Your thoughts? Your neurons ? Your will of trying to discover what happens if you trow a rock? The add on television that induced you the feeling of trying to trow a rock? Or the electricity in the television? Or the clouds that allowed clear television signal ? Or your parents that bought the television? See? There are infinite causes and correlations, and if you want to go to the source you will end up answering always with “because the Big Bang” that would not be useful (and who knows if the Big Bang was the real start of all anyway lol), that’s why we choose reference. That’s why free will is real, because it’s simply a point of reference we choose to allow us to make calculations in our reasonable frame and make decisions. You cannot do that if you take the Big Bang as a point of reference, same, you cannot calculate the car speed if you take your galaxy as reference ;) (well technically you can, but you will need physical laws that are incomplete and doesn’t fit together and doesn’t exist yet (relativity and quantum m.) that’s why relativity is true only if you have a specific point of reference, that cannot be used in quantum mechanics, that has its specific set of rules and assumptions, basically its point of reference)

All reality is described assuming something else and the unfolding consequences, are inherently bound to frame of reference

Best way to explain Frames of Reference👏

i always take out my physics instruments when i'm driving

05:58 = 3 different ways to calculate a problem and all 3 ways give the same answer, KINDA even though the answers might seem slightly different, they actually aren't, some things you just have to understand them with out an explanation, if you can do that you a Genius . Yes

I'm learning something that I found out as a kid who always traveled through bus. Didn't thought it was this important. Thank you sal. ❤️

It seems that there is missing one litlle but important fact.

Frames of reference =
1) Coordinate system (Cartesian, Polar, Cylindrical, spherical and so on...)
+
2) The set of physical reference points (=ground, car and plane [in this video]) that uniquely fix (locate and orient) the coordinate system and standardize measurements.

Coordinate systems arn't mentioned. Implicitly/tacitly there is Cartesian coordinate system with only x-axe in the video.
Otherwise great video!
I always visualize like two or more Coordinate systems move relative to each other. That is how it's in my textbook from physics.

I am in class 8 but intreseted to see this and learn this so that I could be like 10% of Einstein😆

How to write on a mouse pointer like this?

[sharafhussain]

It is so fun to see how much he cares for human rights by not letting us drive the car or plane lol

[idophysics]

Im in uni and have had a brainfart moment, this really helped me get back on track!

[shaikshameem]

Sir, your explanation is excellent.Sir, please explain with reference to earth.

[hussainawni]

An awesome easy way to explain complex idea like this

[darkis]

Thanks I can study this for my CFA tomorrow for 7th grade, thanks again

[mounisanapala]

This video was nothing but the explanation of relative velocity in my view... only at the part, they talk about reference frames & that too not much satisfactory. But nevertheless, a good video, liked it!!

[ahhhello]

Yes thank u soooo much, my physics teacher just made such simple thing sound sooo hard, but ur explanation was perfect!!!
