Mass and Gravity
Name: Nicole S.
I am trying to explain to my 6th graders the idea of
the difference between mass and weight and how gravity pulls on all
objects about the same at 9.8N. They are completely confused as to
the relationship of newtons to lbs. Do you have a clear way of
explaining to them the idea that the gravitational pull is the same on
all of us, but that our mass is different therefore, our weight is
different? They think the pull of gravity should change if our mass
changes. I am stuck. Thanks for your help.
The acceleration, 9.8 m/s/s, is independent of mass, but the total force
on an object is the acceleration multiplied by the mass, and that is
greater for more massive objects.
Newtons and pounds are both units of force.
