No because the astronaut's relative velocity will be approximately the same as that of the spacecraft.
Motion is relative to an observer's frame of Reference.
Observer.
If time is relative to the observer, then "right now" has no meaning. We originally meant that as a facetious response, but that fact is actually the real basis for the whole concept of Relativity ... that "simultaneous" depends on the observer.
as the motorcycle approaches the observer, the frequency increases.
The frequencies are the same, unless the source is moving relative to the observer.
His mass does not change, only his relative weight.
If the man and his equipment weigh 200 pounds on the earth's surface,then their mass is 90.719 kg. (rounded)The acceleration of the package due to a net force of 100N is [ A = F/m ] = 100/90.719 = 1.102 m/s2. (rounded)With this acceleration applied in the direction opposite to his initial velocity,it takes [ V/A ] = 1.814 seconds to stop. (rounded)
The redshift is caused by relative motion that increases the distance from the source to the observer. The faster the source of light is moving away to the observer, the greater the redshift
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
No. There has to be a relative velocity.
Yes, relative to any observer not attached to the earth's surface.
