A satellite has to maintain a constant velocity of 28 800 kmhour in order to stay in earth's orbit however moon has 3 679 kmhour still it does not fall?
It is curious; higher orbits are SLOWER, not faster.
Low orbits are fast; the ISS orbits in 90 minutes or so, in an orbit about 150 miles high.
High orbits are slow. Communications satellites are 23,000 miles up, and take 24 hours. The Moon is 250,000 miles up, and takes 29.5 days.
What else can I help you with?
Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating?
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.
Does a satellite need fuel to keep moving?
Yes, a satellite in orbit requires fuel to make adjustments to its trajectory or maintain its position. However, satellites in geostationary orbit can maintain their position without fuel because they orbit above the same location on Earth.
Why doesn't the Moon travel in straight line and continue in space?
The normal tendency of objects - when no force acts on them - is to move in a straight line, at a constant speed and direction (that is, a constant velocity). However, when there is a force, an object's velocity may be changed. That's what happens to the Moon, as well as to other objects in some orbit. In this case, the force is provided by gravitational attraction from Earth.
What would happen to a satellite orbiting the earth if its velocity increased?
It would move further out of the current orbit. Possibly into an unstable orbit & be flung from earth altogether (however, the people who design satellites are fairly smart and won't allow that to happen)
How can you see a tornado on satellite image?
You can't. Tornadoes descend from thunderstorms, and so cannot be seen from above. You can, however, see the thunderstorms in a satellite image. See the link below for a satellite time lapse of storms tha produce tornadoes.
Will the velocity of an object increase decrease or remain constant as it reaches the ground?
The velocity of an object will increase as it falls towards the ground due to the acceleration of gravity. However, once it reaches terminal velocity, its velocity will remain constant.
Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
Does a car traveling along a curved path at constant speed have a constant momentum?
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
What is the acceleration of an object that moves at constant velocity?
It is called constant velocity. Rate is just another word for velocity. This, however, is dependant upon the path the object is taking. If it is moving in a parabolic path, or a curve of some sort (anything but a straight line), then the object is actually accelerating (as acceleration is a change in velocity OR direction.)
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
When the acceleration is zero what can you say about the velocity of an object?
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.

The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite.

Can a body have constant velocity and changing speed?
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.
How does mass affect velocity?
When mass increases, velocity remains constant if the force applied remains constant. However, if the applied force stays the same, an increase in mass will require more force to achieve the same acceleration, which may lead to a decrease in velocity.
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
When a body has uniform velocity?
When a body has uniform velocity, it is moving in a straight line at a constant speed. This means that the magnitude and direction of its velocity remain constant over time. uniform velocity implies no acceleration present in the motion of the body.
Is a car on a circular track has also constant velocity?
Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.
