MIT BLOSSOMS lessons are designed to make math and science engaging and fun for high school classes!
These lessons have been created by educators from the U.S. and also from many other countries around the world.
Check out the MIT BLOSSOMS website for everything a teacher will need to use these lessons in class. You can also search for a particular language on the website.
Has any one ever seen an experiment proving the hypothesis that air destined to travel over the top of a foil increases its speed when it encounters the leading edge of the foil and begins its longer trip over the top? One could add two pulses of dye into a slip stream so that they travel on either side of a foil. The expected result, according to the explanation of lift in this video, should be the pulses arriving at the trailing edge in exactly the same relation that they arrived at the leading edge despite one pulse having to travel a longer distance. The pulse had to have received a force in the trailing edge direction to increase the speed component of the velocity. What generated the force int he trailing edge direction that increased the speed of the pulse that went the longer distance?
Have you also investigated regarding LWL over the Hull Speed as yet conceptualising the boatbuilding with short LOD with wide Beam but all of my hull concept obtained semi displacements hull as enough to configurate proper ballasting systems using Gaff Rigs as main sail as yet I mention a pocket yacht with 16 or 17' LOD under the 20 or 21 LOA as though I was not properly schooled with degree but technically under the domestic doctrine standards nobody believe me with extra-curricular property especially within these curriculum aren't been part a standard curriculum here, as fell short some degree of misunderstanding enough to call me a delus
I understood sailing dynamics better from this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FCcKeOmYHFY.html childish video, than from the MIT engineering professor here. Cheers
You linear momentum explanation is ignoring friction. And if either of the balls spin, that affects the friction even more. And some of the energy is transferred into the sound so there are other factors at play.
How long would DNA last on a piece of clothing. I am looking at a sixty year old murder. The clothing of the person was stripped off during the murder but perhaps something would still exist on the trheads.
the teacher assumes that the student knows what she's talking about without pointing to. She leaves the exercises with insufficient context to come to conclusions... she never took teaching classes
So the downwind quarter is the fastest quarters to sail.below 90 degrees to the wind. 2.0 times windspeed is maximum boat speed. But perfection is not a realistic goal. Vesta's speed can be reached in a full size sailboat design of normal academic design. If the keeling design is correct and the width is twice the height of the mast or greater.
The stem is halfway between the mast and forestay of the largest sail. This is the point where keeling of the headsails begin and should relative to the sail area ratio of mainsail and headsails.
The sailboat can sail up to twice the speed of the wind but this is theoretically perfect number and not physically possible. 1.5 times the windspeed is a realistic goal but without stem to stern academic keeling design this ambition can't be seen.
The center board should be directly below the mast and ahead of the mass. If you keel the boom the boat heels over before moving forward and has less sail power..
What is usually missing from sailboat design today is keeling design that has lateral resistance ahead of sail effort. The stem to stern academic keeling design reduces heeling over and increases speed of the sail boat. Most importantly this keeling design keeps the boat easily sailing into the wind and the sailor can easily keep the bow to waves and wind. This lateral resistance ahead of the sail area is essential to create lift and have greater speed.
Oh .. I dont get it. Bernoli or whatever air thing is never makes sense It cant generate enough lift to lift a 300 70kg adults and fuel and avionics right ? .. along with its own weight. .. the perpendi doesnr make sense
I wonder how such a well designed system can creat it self by chance !!!!! it is hard for an engineer to buy.. it also goes against all enthropy and propabilities theories.
Why do we have to eat? Michondria, Has baffled me, From learning from the the foods and air we take I is convert to Oxgyen.... Legends and myths I always wondered if man lived I tge carbon age Did he live on Oxgyen Belfast Ireland 🇮🇪 😎
I was under the impression that the proton pump is unidirectional in the counterclockwise direction and that there were gates that return extra and internal membrane states to original ionization.
@@angelustt Actually... now that I look back at it; I may have gotten that wrong. I looked up a Laura Zagar -- there's one that is a Patent Attorney who focuses on water and energy infrastructure... I'm not 100% certain that this is the same person.
fuck your white man science. you have ripped off indigenous Rang elders of which i am one and not even mentioned us. fuck you and this ignorant and racist video.
Sorry to hear that you have a point of view.i believe all videos have value for someone somewher.i liked it for it's detailed content and can refer back to it when I need to explain how it all works.some of this I learnt in my physics at the age of 13.so when I came across it I could relate to all of it
