coconut is mi idol is 100% correct except in question 4 there are two answers that are the same but one is elastic potential energy and the other is gravitational potential energy and you need to choose the one that says gravitational energy.
Coconut Is Mi Idol is correct but Anonymous is also correct with the fact you need to choose gravitational potential energy! Thanks for helping me check my answers guys! :)
