Shift the wavelength of the spectrum.
The most important piece of evidence that shows that the universe is in motion is the Doppler Effect, also termed the red shift. This basically means that objects headed away the observer will have their light bent toward the "red" (lower frequency) side of the light spectrum while objects headed toward the observer will have their light bent toward the "blue" (higher frequency) end of the spectrum. By using the Doppler Effect we are able to that the majority of the universe is in motion, expanding outward.
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.

The motion force
By observing far away stars in our galaxy through a spectroscope, we are able to see the spectrum that appears from the substances in these stars. Each element has a unique spectrum when light is shone through it, so we are able to determine what elements make up certain stars.
Friction inhibits the motion of objects.
They are unrelated to "cause and effect".

forces and motion
Daily motion is a program that allows users to upload videos to the world wide web and has tools that allows the person to edit and format the videos to their liking.
Balanced forces do not alter the motion of objects.
