What happens to the earth orbit speed as it gets closer to the sun?
It increases.
Which planet has the slower orbital speed Saturn or Jupiter?
Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.
Explain why a space shuttle will stay in in orbit around the earth and will not fall to the earth?
The space shuttle is traveling at a speed such that its fall to earth matches the curvature of the earth. As a result, it is "falling" to the earth at the same rate that the earth's surface is rotating away, so it stays in orbit.
Does mars rotate faster than the earth?
Yes, It does. Considering Newtonian physics and assuming circular orbit for simple calculations, this is because in order to equalize gravitational pull of Sun which is higher at Mars orbit, the centrifugal force must be adequately higher(and it rises proportionally to square of velocity).
Is the acceleration on the moon less or more powerful than on earth?
Gravity on the moon is lower than earth since it had lesser mass. The falling object would accelerate at slower speed on the moon compare to earth.
What force acts on the Moon to keep one hemisphere facing the Earth?
Tidal forces made it rotate that way. We can assume that in the far past, it may have rotated faster; tidal forces made it slow down. (In principle, it's also possible that it rotated slower and that tidal forces made it speed up.) Similarly, the Earth is rotating slower and slower; one far day in the future, the Earth will always show the same side to the Moon. Of course, once an object is rotating at a certain speed, it requires no force to make it continue rotating.
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
Is the speed of earth's rotation slowing?
Yes. The energy from the tides ultimately comes from Earth's rotation; due to friction during the tides, Earth's rotation will logically get slower and slower.
Does the sun come up and set at the same speed?
Yes, the effect is due not to the Sun moving but to the Earth rotating and the speed of rotation of the Earth is constant.
An earth satellite in a elliptical moves with what speed?
The speed is variable; faster while closer to the Earth, and slower further away. But the actual speed varies by the orbital distance.
Why earths rotating speed is neglected while calculating the speed of aeroplane?
The air arround Earth has usually the same speed as the rotating Earth itself. That is much different to camparing that with a ship on a river, where you move much faster to the sea by the water stream than to the well-spring of the river.
Why we cannot fell the movement of the earth?
I think cause earth is rotating at a constant speed nd we are well adapted to that speed. Bt I wonder that if earth stopped then we will fall due to momentum or not.
When earth spins at slower speed how many hours in a day would it be?
15 hours
Why you do not feel the earth rotation?
We don't feel the Earth rotating, because we're rotating with it. If it stopped or sped up, we would certainly feel it. It's like riding in a car; when the car is going straight on a smooth road at the same speed, we don't feel it; only when we turn or slow down or speed up.
What will happen if the earth starts rotating at a faster speed?
I'm sure it would effect the earth's electromagnetic field as it is the spinning of the earth's core that creates the field.
What happens to a substance as it approches the speed of light?
Its mass will increase, its length will decrease in the direction of movement, time will get slower. All this is from the point of view of somebody who is NOT travelling with the substance in question, but stays on Earth for example.
Will the earth spin quicker in 100 years?
It is not likely that the Earth will spin quicker, as it has been rotating at nearly the same speed for at least 2,000 years.
