Question

When people say the mass of the star, does it mean the weight of the star or something else?
I would really appreciate it if someone can clarify that for me.
Medal and fan reward!

Answer 1

Mass is the same anywhere in the universe.
Weight depends on the mass and gravity.

Answer 2

Mass is basically a measure of how much material there is. Weight is the force of gravity acting on something and the more mass you have, the more you weigh.

So even though you have the same mass if you were here or on the moon, you will weigh less on the moon than you do on the earth because the force of gravity from the moon is weaker.

Answer 3

I am supposed to answer what determines the lifespan of a star. If I use the words fuse or mass I am supposed to clarify what they mean. I answered that the lifespan of a star is determined by the mass. I thought that mass meant the weight of the star but I'm not sure.

Answer 4

so what exactly is mass in my case?

Answer 5

Mass is an absolute measure of the material in the star.
That is the proper term to use.

Answer 6

okay thanks so much!

Answer 7

You're welcome.
