    I'm having great difficulty working out equations involving energy changes in exercise 2D of the Heinemann textbook. I'm not sure where the PE, GPE or EPE goes most of the time and I'm not being able to think it out logically. Any help/guidance is appreciated!

    Do you mean this booklet?

    It seems like you're using all forms of energy in the beginning of the equation but cancelling them out when they're not present. Is that so? How do you decide which type of energy is present? That is what's confusing me.

    That is correct that is exactly what I am doing.

    I have finally figured it out after running through the workbook. Thank you once again, Mr TeeEm. I can't rep you anymore, unfortunately...
