Question

would your mass change if your on the sun

Answer 1

Your mass would remain the same regardless of whether you are on the Sun, Earth, or any other location in the universe. Mass is an intrinsic property of matter and does not change based on location.

However, your weight would change significantly. Weight is the force exerted on an object due to gravity and is dependent on both mass and the gravitational field strength of the location. The Sun has a much stronger gravitational pull than Earth, so if you could somehow stand on the surface of the Sun (which is impossible due to its extreme temperatures and lack of a solid surface), your weight would be vastly greater than it is on Earth.

In summary, while your mass remains constant, your weight would increase dramatically due to the Sun's stronger gravitational force.
