Force that the Earth exerts on the Moon

[Poppinkrey]

Let's say that the Moon has a mass of 7.4 x 10^22 kg. What's the force that the Earth, and the Sun exerts on the Moon?

 

[Janus]

Just use

$$F_g = \frac{Gm_1 m_2}{d^2}$$

 

[Drakkith]

There's a gravitational force calculator if you search google as well.

Got it, thanks!

One could also use its mean radius, mass, and orbital velocity...

Why does radius matter?

of its orbit.

of its orbit.

Yes, thank you DaveC. Sorry, Drakkith, for not clarifying that.
