The moon has an elliptical orbit around the Earth, although it is almost circular; when the moon is at the closest point to the Earth in its orbit, it moves the fastest, and when it is at the most distant point, it moves the slowest. But the variation is relatively small.

Assume that the moon travel at constant speed in a circular orbit around the earth is the moon's velocity is constant?
yes
The moon revolves aroung earth at a fairly constant speed is the moon accelarating?
The Moon's speed is very constant. There are 2 kinds of acceleration: Linear and Centripital. Centripital acceleration is experienced by a body orbiting another body, like the Moon orbits the Earth, but it does not mean speeding up.
Is the speed at which the earth rotates constant?
No. Earth's rotation speed is affected by the gravitational pull of the sun, moon and planets.
Are there unbalanced or balanced forces on the moon?
Must be unbalanced. Otherwise, the moon would be moving at constant speed in a straight line.
If the moon orbits the earth at a constant speed why is it always changing?
Its speed is not always constant; because of its orbit, it sometimes goes faster or slower. However, its appearance changes because of where it is compared to the earth and sun - when the sun shines on part of it, that part is visible, but where it is in shadow, it is not visible.

Is the spring constant is constant on the moon?
no the spring constant is not constant on moon because there is no restoring force there
What forces act on a moon which is moving around a planet at the constant speed?
Gravity, in balance with centripetal reaction force.

What is the different between constant velocity and constant speed?
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
Why constant is used?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
What is approximate distance between earth and moon?
If you could fly to the Moon at a constant speed of 1000 kilometers per hour, which is the speed of a fast passenger jet, it would take sixteen days to get there.
