Hi there,

While you're waiting for an answer, did you know we have 300,000 study resources that could answer your question in TSR's Learn together section?

We have everything from Teacher Marked Essays to Mindmaps and Quizzes to help you with your work. Take a look around.

If you're stuck on how to get started, try creating some resources. It's free to do and can help breakdown tough topics into manageable chunks. Get creating now.

Thanks!

Well, the PPF shows "the total combinations of goods/services that can be produced when a given number of resources are fully utilised" - thats what you'd say as the definition to get you a mark in the multiple choice (or even data response?) questions.
Think of it like, you have 100 burger buns and 100 pieces of chicken and lamb steaks each. So you can either make 100 chicken burgers and no lamb, or 100 lamb and no chicken - these two points would be on either the x or y axis. Then the "curve" itself comes about because for example you could have: 20 chicken and 80 lamb, 30 chicken and 70 lamb ..... 70 chicken and 30 lamb and so a curve is plotted from 100 chicken to 100 lambs.
If however you're on the inside of this ppf curve, then you're not using all your resources (effectively) e.g you're only using 80 buns instead of 100. On the other hand, it's impossible to be 'above' or 'outside' the PPF curve, as you simply don't have the resources to produce so much at that given time (with 100 buns you can only make a maximum of 100 burgers). However you can SHIFT the PPF out by buying more buns and chicken/lamb, hence increasing your productive capacity
SOrry for the weird examples aha but i hope i helped somewhat, answering these questions is great for my unit 1 revision
