Here are some crazy and incredible physics facts that are worth sharing with your friends and family!
When traveling through water, the speed of sound is even faster — about four times — than when it travels through air. However, it cannot travel through a vacuum.
Nikola Tesla (1856-1943) was a Serbian native who became a naturalized citizen of the United States in 1891. He was known for his design of the modern AC electric supply system.
The blue-tinged banknote features the famous image of the world-renowned scientist on the obverse side. The reverse of the 100 dinar banknote, on the other hand, features a detail from Tesla’s electro-magnetic induction engine.
It can even run as fast as 120.7 kilometer per hour! And no one else can outrun the cheetah, except perhaps the other cheetahs.
From its core, the sun fuses 620 million metric tons of hydrogen per second into 616 million metric tons of helium. And in every second, the sun emits around 4 million tons of mass into energy through light and heat across our solar system.
During sunrise or sunset the sun may appear yellow (sometimes orange or red). It’s because the short-wavelength colors like blue, green and violet are dispersed throughout the atmosphere.
In the optical range, which is between 100-nm to 1000-nm wavelength, the Sun can be treated as a blackbody that has a constant temperature of about 6000 K. However, the radiation flux is stable and has very small changes over the solar cycle. When looked at in the radio frequency band (1 cm to 30 cm wavelength, approximately), the radiance changes considerably based on if the Sun is disturbed or is quiet.
Capillary action is considered an important ability of water to move through materials like tubes. Although water is not the only liquid with such abilities, its unique properties enable it to have better capillary action abilities than most other liquids. Capillary action happens when adhesive forces prevail cohesive forces. For instance, you are drinking water through a straw. We know that the molecules of a water attract each other pretty much, but they are are also attracted to the straw’s plastic. This will lead to the water climbing up the surface of the straw inside. Moreover, the level of the water becomes a bit higher in the interior of the straw. Even so, you can see the better adhesion between the glass and the water.
Did you realize that the car you drive at 50 MPH will use half of it’s fuel just to overcome the wind resistance against the car as it travels? Does that mean that if you drover faster, you would go through your fuel quicker? It is something to think about, hmm?
Now you know why a magnifying glass makes things appear bigger than they are!
So don’t ever confuse it with a “physician” who is more of a doctor!
Every planet has its own unique gravity. Mars has a gravity of 3.711 meter per squared second (m/s²) compared to Earth’s 9.807 m/s².
No wonder that electric eels (actually a type of knifefish, not an eel) have no natural enemies, and they’re one the least endangered animals.
The calorie that you usually see on a food label is actually 1,000 calories or a kilocalorie. Also referred to as “kcal,” a calorie is the amount of energy required to increase 1 gram of water 1 degree Celsius at normal atmospheric pressure.
It makes sense when discussing about calories in food, because food gives us energy to be able for us to do our day-to-day functions. For instance, if you’re never able to burn 100 calories you will simply add on extra unnecessary weight.
This is partly because of the moon’s close proximity to the earth, being just less than 250,000 miles from us.
The NASA radar spotted ice deposits on the moon’s north pole, which amounted to millions of tons. The ice came as a result of the bombardment from meteorites and micrometeorites. Most of them contain water ice, and if you see the large craters on the moon, you realize how big these meteorites are and their impact. Any of the ice that made it through the impact would eventually be scattered throughout the surface. While some of the water ice may be lost due to evaporation to sunlight, many of them would remain in the craters.
He won the award for his important work on theoretical physics, and particularly for his discovery of the law of the photoelectric effect.
