Weight is a measurement of the force on a object
caused by gravity trying to pull the object down. Mars has less gravity
than Earth. Therefore if you were on Mars you'd weigh less because the
force of gravity wouldn't be as strong as it is here on Earth.
Does this mean you would suddenly be thinner on Mars? No. You would
have the same amount of mass as you do on Earth. (Mass is the amount of
stuff inside an object.)
So, on Mars, your mass would be the same as it is here on Earth. But
you'd weigh less because Mars has less gravity than Earth.
