If your mass is 70kg on earth how much is your mass on the moon?

If your mass is 10 kg, then it's 10 kg on the earth, the moon, the International Space Station,

inside Saturn's rings, or halfway to Alpha Centauri. Your mass is yours. You take it with you. It

doesn't change, no matter where you go.

What DOES change is the force that draws your mass toward other masses that happen to be nearby.

The larger the OTHER mass is, the stronger the force is between it and you. The name we give to that

force is your "weight". That's the thing that can change when you take your mass to other places, and

near other masses.
