Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
On the molecular level, the molecules of glass are unchanged by the physical stress that caused breaking. when glass breaks, the only thing that is affected is the intermolecular bonding, not the intramolecular bonding. In addition, it is observable that although there is somewhat of a shape change, there is no color, heat change or gaseous creation that would imply that a chemical change has taken place.
yes
Chemical change

Actually breaking a dinner plate is not a chemical change. A chemical change is like putting sugar into a hot cup of water or tea.
Yes, as it's still glass. There is no chemical/molecular change.
A physical change
No, melting ice is a chemical change where as carving ice is physical.... Another example is chewing food is physical where as enzymes in your saliva breaking down the food is chemical.
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Since in breaking down there is no chemical change it's a physical change
This is a physical change.
