How does gravity affect mass and weight?

Mass changes with gravity; weight stays the same. Mass stays the same, weight changes with gravity. Mass stays the same; weight stays the same. Mass becomes weight in accelerated frames.

Correct Answer:

Mass stays the same, weight changes with gravity.

Explanation:

Mass is the amount of matter in an object and doesn’t change with location. Weight is the gravitational force acting on that mass, so it depends on how strong gravity is. The relationship is W = m × g. Because gravity (g) varies—from Earth to the Moon to space—weight changes with gravity while mass stays the same. For example, you’d weigh less on the Moon due to weaker gravity, even though your mass is unchanged. If gravity were eliminated, weight would be zero while mass remains.
