Changes

#Is there a difference when you hold each of them?

#Is there a difference when you hold each of them?

#Is this due to inertia? Am I changing anything when I am holding?

#Is this due to inertia? Am I changing anything when I am holding?

#What might this difference be due to?

#If I stop holding, what happens?  Will it fall?

#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

#Have you ever seen something fallen from a height - or even a fruit from a tree?

#We will study more about this - but mass also interacts with other masses; this is called gravitational property.  We already saw that is has an inertial property

#If it is changing its position and moving (falling) there must be a force?

#The Earth is not touching the object, but still its mass has an effect on the mass on my hand

#Where do you think the force is coming from?

#Is it possible that forces can also act without touching?

* '''Evaluation (Questions for assessment of the child)'''

#Does mass have both inertial and gravitational property?

#Does gravitational property depend on size? Or mass?

#If an object has inertia, when I drop the object why does it fall?

#Do you feel the gravitational effect of the Earth?
