Answer 2

This is a realy difficult, perhaps trick question, to ask a class 9 student. - So I suggest you flip it back to the teacher/class.

  With respect to working model of energy and motion, just say Isaac Newton looked at this some time ago and &quot;I am not going to question his logic or analysis in this forum&quot;.

  With respect to natural resources, you can say that the Earth as a Living System is a prime successful example and people are still studying it and continue to find it to be more complex than they thought. See the Gia Hypothesis.
