Mass and weight are similar but not the same thing. in which of the following examples would the objects weight change, but made stay the same? an astronaut travels from the earth to the moon a child grows taller an overweight person goes on a diet a snowball rolls downhill and picks up snow making it grow

An astronaut travels from the Earth to the Moon.

Weight depends highly on the gravity that’s pulling you down (and the mass of the body in question) — in this case, Earth’s gravity.
An object will have the same mass at any point in space — be it on Earth or a far-away planet — but since Earth’s gravity fades the further into space we go away from Earth, the same way, weight will change. That’s the key difference between mass and gravity — mass only depends on how much matter a body is made of, while gravity depends on mass and gravity.
