1. The problem statement, all variables and given/known data I have a test on Energy in a few days, I'm in the top science class at my school (grade 9). 2. Relevant equations The test is on stuff like, Kinectic Energy, Potentional Energy, Renewable Energys etc. If anyone on here can help me, It would be greatly appreciated. If I left anything out that you may need please tell me & I'll try my best to answer.
