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.
What type of motion does a bird flying in the sky have?
random motion
What are the examples of non - periodic motion?
the answer is when an object moves repeatedly but randomly and without periodicity than its motion is said to be an non periodic motion
What is the effect of buoyancy to the object?
The effect of buoyancy is to reduce the apparent weight of the object when it's introduced into a fluid. Depending on the density of the object compared to the density of the fluid, the object's apparent weight could be reduced to zero (beach ball floating in the pool), or even to a negative value (helium party balloon heading for the sky).
Why does the size and direction of a shadow change?
Because the sun moves through the sky, or at least it appears to do that. Since the sun's position changes with respect to objects on the earth so do their shadows.
What causes the apparent movement of objects across the sky during day or night on earth?
The rotation of the earth is what gives motion to the heavens.
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.
On the night when you were watching the Moon at sunset and then at 1000 its overall motion in the sky during that time was?
The Moon's overall motion (apparent motion) in the sky was from East to West.
The apparent motion of stars is due to movement of?
The rotation of the Earth makes the stars appear to move in the sky.
What does the length of shadows made by the Sun throughout the day tell you about the Suns apparent motion across the sky?
If the shadows are longer, that means the Sun is lower in the sky.
In which direction does the northern sky seem to turn?
The apparent motion is anti-clockwise..because the Earth is turning the other way........
Do the stars move across the sky?
Yes, stars do move around in the sky, but their apparent motion is very small, such that it would require centuries to note significant change in their positions.
Star which do not change its position in the night sky?
The only star that does not appear to move in the Sky is Polaris, the North Star. (Actually it does move in a TINY circle, but the apparent motion is too small to notice.)
What causes the apparant movement of stars in the sky?
The real motion of stars is hardly noticeable even over a period of many years. It's the Earth's daily rotation the is the main cause of their apparent motion. (Stars are so far away that the Earth's revolution around the Sun hardly cases any apparent motion.)
How much does a star in the sky move in 8 weeks?
Not at all. When compared to the other stars, there is NO star that shows any apparent motion in as little a time as 8 weeks. The star with the fastest "apparent motion" is Bernard's Star, sometimes called the "runaway star". If you could memorize the night sky when you were young, and compare it to the sky when you are dying of old age, you MIGHT be able to notice this one star having moved, just a little.
What is the line that the sun traces across the celestial sphere?
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
Major advantage of Copernicus' Sun-centered model over the Ptolemaic model?
It offered more natural explanation for the apparent retrograde motion of planets in our sky.
