scientific notation
a system for writing large or small numbers accuratley
weight is a measure of
the pull of gravity on an object weight will change when gravity is different
your mass on the moon is
1/6 as much as on earth because gravity is 1/6 on the moon
your weight in outer space is 0 llbs because
there is no gravity in outerspace
you weigh less in the mountains because
gravtiy is weaker at high altitude
temperature
a measurment of the average kinetic energy of molecules
mass is a measure of
the amount of matter in an object the amount of matter is the same on the moon or on the mountains
mass is the same anywhere
