When is a body said to be in motion in relation to an observer?
when position of the body with respect to an observer change with time then the body are said to be in motion.
What does the apparent motion of objects in the sky depend?
The apparent motion of objects in the sky depends on the motions of Earth.
A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called?
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
What is the definition of gyratory motion?
an object rotating about a vertical axis also keeps rotating in its own position and this results in gyratory motion. hope it helps. :)
Why is a reference point is important when observing motion?
Motion is a relative to each other. You presume that the observer is at stable point. Which is never so. Every thing in the universe is moving and the motion is taken in relation to the observer.
What is a parallax error?
Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
Motion is described with respect to a what?
With respect to a state of rest or apparent rest.
When is a body said to be in motion in relation to an observer?
when position of the body with respect to an observer change with time then the body are said to be in motion.
What is the term for the apparent shift in position of distant objects due to motion of the observer?
The term you're looking for is "parallax." Just a caution for you not to confuse parallax, which does answer your question, with the retrograde motion of some of the planets, which is related but different.
What is a stars apparent shift in position?
Motion
An object is in motion if it changes position relative t a?
Observer.
What does the apparent motion of Polaris from sunset to midnight for an observer in northern Canada look like?
Polaris does not appear to move.
What does the apparent motion of objects in the sky depend?
The apparent motion of objects in the sky depends on the motions of Earth.
A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called?
The Doppler effect.The Doppler effect.The Doppler effect.The Doppler effect.
What happens when a star's spectrum is redshifted as a result of the Doppler effect?
With respect to light, the Doppler effect refers to the apparent change in the frequency (and wavelength) of electromagnetic radiation due to the relative motion of the source relative to the observer. When the source (i.e. a star) moves AWAY from the observer, there is an apparent rarefaction (expansion) in the wavelength of emitted light (i.e. frequency decreases), causing a shift in the emission spectrum towards the red side. This is known as redshifting --> the star is moving away from the observer. The opposite happens in blueshift, when the source moves towards the observer.
What affects how an observer views motion?
The observers motion in relation to what he observes.
What direction relative to an observer on the earth's surface does the moon travel in its orbit?
In this case, there is 'true' motion, and there is 'apparent' motion. To an observer on earth, the moon 'appears' to rise in the east and set in the west, just like the sun. But in fact the moon travels from west to east in its orbit around the earth. From a perspective far about the earth and to the north, the moon travels counter-clockwise around the earth. It is the relatively rapid daily spin of the earth from west to east that causes the apparent motion. The moon takes a whole month to orbit earth; in that time 27+ days have gone by on earth.
