for sacs do the definitions have to be word for word?
Also what does it mean by list 2 physical health dimensions?
Could i say
Energy levels
The physical capacity to perform tasks and physical fitness?
The definitions should be very close so as to not forget important detail e.g. in the definition of under-5 mortality rate, you don't want to miss out on the "per 1000 live births" component of the definition. For that reason, some definitions should be word to word

Also, definitions endorsed by organisations like WHO, UN, VicHealth etc need to be word-to-word as those are "official" definitions

Listing 2 physical health dimensions is mentioning two indicators/factors which can help us to gauge someone's physical health

So yes energy levels and physical fitness are correct

You can also mention:
Body Weight for Height, Blood Pressure Levels, Blood Glucose Levels, Blood Cholesterol Levels, Lung Capacity and Function, Immune Response, Diet, and Flexibility of Muscles and Joints - as we can sort of determine a person's physical health through these indicators/factors
