How are all of the planets kept in orbit around the sun?
all the planets stay in orbit around the sun because of the sun's gravitational pull. The high orbital speed that keeps the planets from falling all the way into the sun and since there is no friction in the vacuum of space , that speed dosen't slow down.
When does a planet move fast or slow?
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
What happens during a space walk does the International Space Station stop or it continues at the same speed?
The space station continues at the same speed. The spacewalker will also travel at the same speed. Their relative speed however will be near zero however because they are travelling together. In effect their is no real way for a spacecraft to speed up or slow down without changing its orbit.
Light from the sun travels through space to the earths atmosphere What will light waves do when they move from empty space into matter made up of different gases?
They will slow down slightly compared to their speed in vacuum, they will bend slightly as they enter the atmosphere, and they will follow a path through it that continues to curve slightly.
What does gravity have to do with the moon and the sun?
Gravity has to do with everything in the universe. Gravity pulls the Moon toward the Earth, but its orbital speed prevents it from falling into it (it falls"around" the Earth in a slightly elliptical orbit). Similarly, the Sun's gravity keeps the Earth and Moon, and the other planets, in their orbits.
What causes the moon to speed up or slow down in orbit?
time of the season
Where is the speed of light at its fastest?
The speed of light is fastest in a vacuum. All other media slow the speed of light down, albeit very slightly.

What happens when an object in orbit looses speed?
If loss of speed does not throw the object's trajectory out of orbit, then the object will descend into a lower orbit, in accordance with the formula r=v2/a, where r is the radius of the orbit, v is the orbital velocity, and a is the acceleration due to gravity (9.8 m/s2). If there is atmosphere, even very thin atmosphere (as there is for the International Space Station), then as the object descends to a lower orbit, the atmospheric drag will cause the body to slow down even more, which causes the body to descend to a lower orbit, where the atmosphere is thicker, and thus the drag is stronger, and a vicious circle will eventually cause the body to spiral into the surface below.
Is polar orbit faster than regular orbit?
The speed it takes to complete and orbit is based on the altitude. Each altitude has a specific speed. One cannot be in a low orbit, say 160 miles perigee that takes 90 minutes to complete, and go faster at 160 miles perigee and take 80 minutes. If one increases their orbital velocity, it increases their altitude AND it makes the orbit take longer to complete. Its kind of a crazy way to do things, but we're talking about rotational physics, not linear (which we are more accustomed to). How backwards is this?? Let's say you're trying to reach the space station and it is ahead of you in orbit. If you want to go FASTER in orbit, you actually need to SLOW down, drop to a lower orbit, which will be faster, until you slightly pass the space station. THEN you speed up, go to a higher orbit where the space station is, and link up. There is a reason astronauts are good at math and that computers are necessary in spaceflight!
What causes objects to speed up or slow down?
an outside/net force
What causes an object slow down or speed up?
an external net force acting on it
What causes an object to slow down or speed-up?
an external net force acting on it
What causes an object to slow down or speed up?
an external net force acting on it
Can A force can cause an object to change its speed?
Yes,because if a force is getting weaker it causes the speed to slow down but if the force is getting stronger it causes the object to move faster.
Why do planes and space shuttles fly at a different speed?
The space shuttle goes into orbit around the earth. In order to stay in an orbit, something that is orbiting has to go at the right speed for that orbit. The orbit the space shuttle goes into has a speed of around 17000 mph. If it went faster, it would go up higher into space away from the earth. If it went slower, it would not have enough energy of motion and it would fall back to earth. The shuttle's big rockets don't just lift it up into space, their main purpose is to give the shuttle this enormous speed so that it can stay in its orbit. A plane engine is not strong enough to make the plane go this fast, but if it did somehow go this fast it would burn up. When it is time to land, small rockets on the shuttle change the orbit so that it goes into the air. The air slows the shuttle down, and it starts to come down faster since it doesn't have enough speed anymore to stay in orbit. The air rushing past the shuttle has friction with the shuttle and gets very hot. As the shuttle goes through the air, it slows down from this friction, until it is finally going slow enough to land. When it lands the shuttle has slowed down to the speed of a plane.
