question 18 of 28 which of the following statements best summarizes the law of conservation of energy before and after a change in a system? a. pe (initial) = ke (initial) and pe (final) = ke (final) b. pe (initial) = pe (final) and ke (initial) = ke (final) c. pe (initial) + ke (initial) = pe (final) + ke (final) d. pe (initial) + pe (final) = ke (initial) + ke (final)

question 18 of 28 which of the following statements best summarizes the law of conservation of energy before and after a change in a system? a. pe (initial) = ke (initial) and pe (final) = ke (final) b. pe (initial) = pe (final) and ke (initial) = ke (final) c. pe (initial) + ke (initial) = pe (final) + ke (final) d. pe (initial) + pe (final) = ke (initial) + ke (final)

Answer

Brief Explanations:

The law of conservation of energy states total mechanical energy (sum of potential and kinetic) remains constant in a system. Initial total energy equals final total energy.

Answer:

C. PE(initial) + KE(initial) = PE(final) + KE(final)
