* '''Developmental Questions (What discussion questions)'''
#Is there a difference when you hold each of them?
#Is this due to inertia? Am I changing anything when I am holding?
#What might this difference be due to?
#This is due to a property called weight which is because the mass of this object interacts with another mass - that of the earth. We call this weight
#We will study more about this - but mass also interacts with other masses; this is called gravitational property
