We call this weight − #We will study more about this - but mass also interacts with other masses; this is called gravitational property − #The Earth is not touching the object, but still its mass has an effect on the mass on my hand − #Gravity can act at a distance between two masses − * '''Evaluation (Questions for assessment of the child)''' − #Does mass have both inertial and gravitational property? − #Does gravitational property depend on size?
