how would your weight change on the surface of an earth sized planet whose mass was greater than earths? why?

Sagot :

Gravity=Gm1m2/r²
G=Gravitational constant
This equation describe the gravity between two objects, which is you and a planet.
if mass become greater, no matter of which object, the Gravity become bigger too.
So your weight will become greater.
lin is right but your mass does not change and your weight does.your weight changes because of the gravitational pull on earth comparing to another planet
