The acceleration in freefall on the Moon is about 1.622 meters/sec2 (approx. 0.165 Earth g).

The acceleration due to gravity can be found using Newtons law of Universal Gravitation.

The mass of the moon is 7.36x10^22 The radius of the moon is 1,737.4 kilometers or 1.7374x10^6 meters and newtons gravitational constant is 6.67x10^-11(m^3)/(kg*s^2).

Using this information we can use the formula a=(G(m2))/(r^2) where a= acceleration on the moon G is gravitational constant and m2 is the mass of the moon.

So... a=(6.67x10^-11(m^3)/(kg*s^2)(7.35x10^22kg))/(1.73x10^6m)^2 so acceleration on the moon a=1.62631m/s^2

Or you could do it the easy way since gravity on the moon is 1/6 that of earth the acceleration of gravity of the moon would be 9.8/6=1.63m/s^2

Well... not exactly. The Moon is constantly accelerating towards the Earth, but its sideways velocity is great enough that it never actually gets there. This is more or less the definition of "orbit".

The situation on the moon is similar to the situation on earth as regards gravity. The gravitational constant here actually varies a bit from, say, the equator to the poles, but its pretty much the same. On the moon, there is a gravitational constant associated with this celestial body as well. On our single natural satellite, the gravitational constant is 1.622 meters per second2 or 0.165 4 g. (The g is earth's gravitational constant.) As the moon isn't perfectly round (as earth isn't perfectly round), there will be a slight variation across the lunar surface. But not much.

No. Earth is not an exact sphere; some places are closer to the center than others. Also, at the equator the Earth rotates away from any falling objects. This is sometimes expressed as if the rotation caused a centrifugal force. Also, on a mountaintop Earth is a bit farther away than at sea level. All this causes slight differences in the force of gravity. The Moon rotates slower than Earth, so there won't be that many difference, but there are still differences in height.

Note that there is a big difference in the force of gravity - and hence, in the acceleration of a falling object - between Earth and Moon.

The acceleration of gravity on the moon is approximately 1.62 meters per second squared.

yes because speed can be increasing or decreasing or even turning and when the moon is revolving around the earth it is changing speed

Why is the moon said to be accelerating?

I believe the reason is because the moon gets a tiny bit closer to the earth ever year.


The distance from earth to the moon is about 240000 miles the Ulysses spacecraft can travel about 30000 miles in one hour how long would it take Ulysses to travel 240000 miles?

80 hours. It's different going from the earth to the moon because you travel along large ellipses. There is also the issue of accelerating and decelerating. If Ulysses flew by the earth and moon in a straight line, it would only take eight hours to pass.


In what sense is the Moon falling toward Earth?

Possibly that the moon is accelerating towards the earth constantly, as gravity is pulling it towards us. the reason it doesn't crash into us is that it is moving at 90 degrees to us. Because it is always being pulled towards us but is also moving to the side, it ends up orbiting us. I hope this explanation is simple enough to answer your question.


Why do astronauts feel gravity in space?

There is always gravity between two objects. If the astronaut is in a stable orbit around an object, he/she will not sense any gravity. If he/she is standing on the object, such as the Moon, there will be a sense of gravity. In the case of the moon, its gravity is about one sixth that of Earth. Also, if the spacecraft is accelerating, the the reaction force of the engine will cause the sense of gravity as well.There is also gravity between the astronaut and the spaceship, but that is so small that it will generally not be noticed.


Can the moon have a moon and the Moon's moon has a moon and the Moon's Moon's moon has a moon?

In theory, yes.

What is causing the moon to accelerate?

The Earth. The Earth and Moon are bound together by gravity and the Earth's tides (caused by the Moon) are accelerating the Moon and slowing the spin of the Earth. This means that the Moon is slowly getting further and further away from Earth.

What does weight mean how is it measured?

Mass is the quantity of matter in an object. If an object is subject to an accelerating force, then it has weight. Your weight on the Moon will be about one-seventh of that on the Earth. Because of its much lower gravitational force.
