When driving a car it is important to know how fast that car is going. The speedometer gives a instantaneous speed reading of the vehicle at any given time. Knowing the units the speedometer is displaying is very important. Driving in an area with a posted speed in kph and reading the ...
So if you were theoretically able to hitch a ride on the Parker Solar Probe and take it on a detour from its sun-focused mission to travel in a straight line from Earth to Mars, traveling at the speeds the probe reaches during its 22nd solar flyby 430,000 mph (692,000 kph), the t...
Considering the speed at which a skydiver is typically free falling -- about 120 mph (193 kph) -- and the lack of options if something goes wrong, a parachute rig needs to be incredibly reliable. There's a lot of popular interest in the fine art of parachute packing. It has all the...
The average skydiver plummets towards the surface of the Earth at a rate of 120 mph (193 kph) and can soar horizontally at 30 to 60 mph (48 to 97 kph). Typical wingsuit flyers fall at a rate of 50 to 60 mph (81 to 97 kph) and can jet through the air at 70 to 90 mph (11...
Mounted on a very low propulsion platform that can be driven over without damaging it, guided soft targets can be driven up to 80 kph (~50 MPH), and include braking controls. Some manufacturers specify that they can be controlled within 10 cm. ADAS soft targets are very important for Euro...
A typical Perseid meteoroid (which is what they're called while in space) moves at 133,200 mph (214,365 kph) when it hitsEarth's atmosphere(and then it is called a meteor). Most of the Perseids are tiny, about the size of a sand grain. Almost none of the fragments hit the ground...
