Physical Science Question 1

If no friction acts on a diver during a dive, then which of the following statements is true?

A.The total mechanical energy of the system increases.
B.Potential energy can be converted into kinetic energy but not vice versa
C.(KE+ PE)beginning = (KE + PE)end
D.all of the above


Could you please help us a little by telling us what you think the answer is and why you think that? Otherwise, we are just filling in the blank for you and there is no teaching (and no learning) going on. We want to help you LEARN. We aren't interested in DOING the work. We already know the answers. Thank you for using Jiskha.
