Question

What does the extended work-energy theorem (including gravity) show is conserved?
Options
A Kinetic Energy
B Potential Energy
C Total Mechanical Energy (KE + PE)
Correct Answer
D Power
Correct Answer

Option C is the correct answer.

Detailed Explanation

When only conservative forces like gravity do work, the extended work-energy theorem leads to KE_f + PE_f = KE_i + PE_i. This shows that the total mechanical energy (E = KE + PE) remains constant and is conserved.

Hint

The sum of kinetic and potential energy doesn't change.
