Newton's Cradles Explained⁉️ : - • Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. ... • When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward. ... • The last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction. ... • The device is named after 17th-century English scientist Sir Isaac Newton. It is also known as Newton's pendulum, Newton's balls, Newton's rocker or executive ball clicker. ... • A typical Newton's cradle consists of a series of identically sized metal balls suspended in a metal frame so that they are just touching each other at rest. ... • Each ball is attached to the frame by two wires of equal length angled away from each other. This restricts the pendulums' movements to the same plane. - #newtonsays #physicsvideos #physicsexplained #physics #momentumlaw #newtonscradles #amazingphysics #education #educational #educationalvideos #studyvideos #interestingphysics #physicslaw #sciencevideo #sciencevideos #scientificvideos #practicaleducation #practically #elearning #scienceclass #engineeringlaws #educationalvideo #educationalcontent #educationalvideos #studycontent #proactiveducation - @proactiveducation (at A Must Watch Video) https://www.instagram.com/p/CAo7sOlBVKp/?igshid=rfouvez0mazl

Reaction Between Mentos & Coke EXPLAINED⁉️ : - • Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve. ... • Your average two litre bottle of Coke will contain about fifteen grams of dissolved carbon dioxide. ... • When you open a bottle of a carbonated drink, you release the pressure. As the carbon dioxide is less soluble at lower pressures, it starts to leave the drink in the form of small bubbles. ... • Though the surface of a Mentos candy may look smooth, at a microscopic level it’s full of pits, peaks, and craters, like a miniature version of the surface of the moon. ... • These pits, peaks, and craters are referred to as nucleation sites. They provide a surface for the carbon dioxide bubbles to form on, and allow them to form much more rapidly. ... • That paltry fifteen grams of carbon dioxide in the bottle might not sound like much, but as it comes out of solution in the bottle it can expand to take up up to 8 litres in volume. ... • This explains why the drastically increased formation of bubbles after adding Mentos to the bottle leads to the geyser of Coke shooting out of the top moments later – there’s nowhere else for the bubbly liquid to go but up! - #educationalvideos #physicsvideos #physicsexplained #cokeandmentos #mentosandcoke #amazingphysics #interestingvideos #physicalreaction #chemicalreaction #interestingeducation #practical #practicaleducation #educationalcontent #scienceexplained #education #educational #educationposts #proactiveducation - @proactiveducation (at Sponsored) https://www.instagram.com/p/CAga8cFhbmw/?igshid=1ad8cst1ke633
