How to use it?
- to show the concept of physical change (gentle throw so no change occurs, then increase energy to show physical change)
- to show the concept of activation energy (it is only activated when enough energy is put into system)
- to show the concept of transitional vs. rational energy (sliding motion vs rotational motion)
- to show the concept of isomerization (one molecule changes to another with the same atoms, but different arrangement)
