It is easier to throw away a bullet of 100 gram, than a canonball of 100 kilogram. So I asked myself... Is there a relation between mass and the maximum speed?
Current Maximum Velocity for some Objects
|Object ||Current Maximum Velocity |
|foton(0.0...1gram) ||300.000 km/sec (speed of light) |
|elektron(-) ||250.000 km/sec (20% error - electronmicroscopy) |
|proton(+) ||200.000 km/sec (50% error - cyclotron) |
|0.01 gram ||15,8 km/sec = 57.000 km/hr ( Physics News ) |
|2 gram ||24.000 km/hr (NASA) |
|10 gram ||17.000 km/hr (T5) |
|17 gram ||13.000 km/hr (ARF) |
|1 kilogram ||4.000 km/hr (summary of some experiments) |
The higher the mass, the lower the maximum speed.
All experiments were done in airless tubes.
Since there is more energy and momentum lost during 1000 seconds (a ballistic rocket), than in the case of 0.001 second (a bullet), and since the laws of physics are the same, i.e. the conservation of energy and momentum,
the current maximum velocity of a rocket is LESS than the current maximum velocity of a bullet in an airless tube. Theoretically, it is possible to get any velocity by the use of multi-stages, but experimentally, NOT one rocket has already had more speed than the maximum velocity of a bullet in airless tube.
In the air and at ground-level, the highest speed is 1.190km/hr .
High in the sky and only at the equator and only with a flight to the west, airplanes can get 2.860km/hr and nothing more, due to the rotation of the earth (40.000km in 24 hours = 1.666km/hr).
This is the reason why the Concorde is NOT supersonic from NY to Paris.
I will give all my money (and even my life) to the first person who knows a scientific publication, f.i. in PHYSICAL REVIEW, that contradicts the current 28.800km/hr-limit.
