Cans of Word Worms: Now, Weight! Part Four

So here comes the "hardcore" physics part of the story.  Weight and mass are not the same thing. As defined in Part Three, mass is a constant, and weight changes depending on the force of gravity. This is why people become weightless in space, but they still have mass, because weight is determined by the force of gravity on mass. No gravity, no weight.
