What is the diffrence between mass and weight?

Answer 1

Mass is defined as the amount of matter an object has.Mass is a measure of how much inertia an object shows.

On The other hand,

The weight of an object on earth depends on the force of attraction (gravity) between the object object and earth. We can express that force as an equation:

F = G[M m/r2] ,

where F is the force of attraction, M is the mass of the earth, m is the mass of the object, and r is the distance between the center of mass of the two objects (G is called the Gravitational Constant)

Answer 2

-- The more water you seal inside a bottle, the heavier the bottle is.

-- If you take that bottle to the Moon, it still has the same amount of water in it,

but it weighs much less there than it weighs on Earth.

-- Mass is the matter/material/stuff that an object or a person is made of.

The more mass it has, the heavier it is.

-- If that object or that person goes to the moon, it still has the same mass,

but it weighs much less there than it weighs on Earth.

-- Mass is the material that makes up an object. It doesn't change when the

object travels around.

-- Weight is the gravitational force between that object and other objects,

like planets and moons. That force changes, depending on the mass of the

planet or moon you happen to travel to.

This subject is a constant source of confusion for many people, and

we get questions about it all the time on WikiAnswers. I've tried to

explain it in many different ways, and this answer is a new approach

for me. I'm happy with it, and hope you are too.
