slowing down by just three ten-thousandths of the speed of light. But light passing through a diamond slows to less than half its typical speed,PBS NOVAreported. Even so, it travels through the gem at over 277 million mph (almost 124,000 km/s) — enough to make a difference...
Since the ring gear is spinning, the planets have to spin, which causes the sun gear and generator to spin. As the car accelerates, the generator spins at whatever speed it needs to in order for the engine to remain off. Once you reach about 40 mph (64 km/h), the gasoline engine ...
Once a storm has wind speeds of 38 mph (58 km/h), it is officially a tropical storm. At 74 mph (119 km/h), the storm has reached hurricane levels. At that point, scientists use a 1 to 5 scale known as the Saffir-Simpson Hurricane Wind Scale to classify hurricane strength, with C...
For a jet going slower than the speed of sound, the engine is moving through the air at about 1000 km/h (600 mph). We can think of the engine as being stationary and the cold air moving toward it at this speed. A fan at the front sucks the cold air into the engine and forces ...

You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. That’s 1,040 miles/hour. Just think, for every second, you’re moving almost half a kilometer through space, and you don’t even feel it. ...
The cool thing about the Voyagers is that even though their original missions are now long over, they’re still zooming outward. They’re both ridiculously far away now and going super fast. Voyager 1 is the faster of the two, going 38,000 mph (61,000 km/h)—so fast that it would ...
