Effect of gravity of mass and weight

How gravity affect mass and weight?

• Mass is a measure of the amount of matter that an object has or how much stuff it is made up of. While the weight is a measure of how much gravity pulls on a mass or object
• The weight of the .object depends on gravity at that place while mass is always a constant at any place and any time.
• On the moon, there is less gravity pulling on the object so their weight is less. 
• For example, a rock that weighs one pound while the earth will weigh less than that if it is taken to the moon.
• But does its mass change just because it is on the moon? No, it is still the same size and looks the same. It just has less gravity pulling on it, so it weighs is less.
• That is why an object that seems heavy to use on earth ends up being light enough to float around if they are taken into space.
• Something similar happens is very high places like tall mountain peaks.
• There is less gravitational pull in high places, so you would weigh a tiny bit less on the top of Mt. Everest.
• This is because the peak of the mountain is higher and further away from the center of the earth, so the pull of gravity is that spot is weaker than at the bottom of the mountain.
• Even if they weigh less because of a change in gravity force on your body, your body' s mass of still the same.
• As your body grows you will have more mass which also means you will weight more. That's because when you are on the earth, the amount of gravity that pulls on you stays the same.
• So when your mass changes, so do your wright.
