Gravitational field of the moon

In summary, the gravitational field of the moon is approximately one-sixth of Earth's gravitational field and is measured using the unit "m/s^2". It affects objects by pulling them towards the moon's center with a force proportional to their mass. The field varies across the moon's surface due to the uneven distribution of mass. Compared to other celestial bodies, the moon's gravitational field is weaker than Earth's but stronger than smaller objects like asteroids. Other planets, such as Jupiter, have much stronger gravitational fields than the moon.

[SOLVED] gravitational field

Homework Statement


How much work is done by the Moon's gravitational field as a 1100kg meteor comes in from outer space and impacts on the Moon's surface?


Homework Equations



W=GMm/r

The Attempt at a Solution



W=6.67 X 10^-11(6 X 10^22)(1100kg)/1.5 X 10^6
=2.9 X 10^9

Thank you very much

You should be getting the correct answer as long as the numbers you're using are correct. Check that value for the radius of the moon. Shouldn't it be 1.7*10^6 m? If so, your answer may be off a little bit.

FAQ: Gravitational field of the moon

1. What is the gravitational field of the moon?

The gravitational field of the moon refers to the force of gravity exerted by the moon on objects on or near its surface. It is approximately one-sixth of the Earth's gravitational field.

2. How is the gravitational field of the moon measured?

The gravitational field of the moon is measured using a unit called "m/s^2" (meters per second squared). This unit measures the acceleration due to gravity on an object, which can then be used to calculate the gravitational field.

3. How does the gravitational field of the moon affect objects on its surface?

The gravitational field of the moon affects objects on its surface by pulling them towards the moon's center with a force proportional to their mass. This is what causes objects to have weight on the moon.

4. Does the gravitational field of the moon vary across its surface?

Yes, the gravitational field of the moon does vary across its surface. This is due to the uneven distribution of mass on the moon, with some areas having denser material than others. As a result, the strength of the gravitational field can vary slightly in different locations on the moon's surface.

5. How does the gravitational field of the moon compare to other celestial bodies?

The gravitational field of the moon is much weaker than that of Earth, which has a gravitational field of around 9.8 m/s^2. However, it is stronger than the gravitational field of smaller objects, such as asteroids or comets. Other planets, such as Jupiter, have much stronger gravitational fields than the moon.
