You shouldn't be using the internet to find out the answers to kerboodle!
Punnet square? I think so...
Well, honey, light for a torch is a form of electromagnetic energy, while kinetic energy is the energy of motion. So technically speaking, they're both forms of energy, just strutting their stuff in different ways. Hope that clears things up for ya, darling.
The best way to revise is; 1. Write all your notes down and key information on some paper. Read through it, memorise it. 2. watch TV for 10 mins, or keep your self occupied for 10 mins (NOT REVISING). 3. After 10mins, scan quickly through your notes and say them out loud. Say as much as you can without looking at your notes, walk around if you have to, shout whatever helps you. This is how I revise, and it's great. I usually have some music in the background just to lighten the mood and it usually motivates me to achieve what I can! Good luck! Hope I helped! There is also a brilliant site called 'Kerboodle'. It has all the AQA text books you use at school, so that has pretty much everything you need for GCSE! Take a look, what have you got to loose? Good luck again!:)
