What is the speed of a jet stream? What kind of speed is registered by an automobile speedometer? Whats the fastest mph a human has run? What is the difference between average and instantaneous speed? What is the speed of sound in water?
What if the speed of light was not constant? What if you traveled faster than the speed of light? What can travel at the speed of light? What is the speed of light per minute? How to calculate the speed of light. What is the speed of light in mph?
(760 mph) is a good first answer, it isn't always true. let's look back a the wave of people in a football stadium. what would make this speed change? two things could clearly make a difference. suppose the stadium wasn't full but instead about every other seat was occupied. this ...

And this is the one shown in the film, which they claim should be pure water: Pond with low aluminum in the sediment. The film mistakenly claims the level are high by comparing them to water levels. Note the rocks (8% aluminum) that line the edges, and the bottom. ...
Similarly, when an airplane reaches supersonic speeds, it surpasses the speed of sound, currently traveling at approximately 700 mph (1,127 km) in air at sea level. This is when the aircraft "breaks" the sound barrier. Birth of the Sonic Boom As the aircraft maintains supersonic speed, al...

fraction of stride cycle that a given foot is in contact with the ground; i.e., 1 means the feet never ever leave the ground; 0 means that the animal never touches the ground and thus is truly flying) on the x-axis, and stride frequency (SF; stride cycles per second) on the y-...
Little wonder then why the speed of light is the metric used to determine astronomical distances. When we say a star like Proxima Centauri is 4.25 light years away, we are saying that it would take – traveling at a constant speed of 1.07 billion km per hour (670,616,629 mph) – about...
"Even smaller ones can be locally dangerous: Imagine trying to walk through a 3-inch deep mass of wet concrete moving at 30 mph," according to the California Department of Conservation website, https://www.conservation.ca.gov/. The speed of debris flows is what distinguishes them from large...
