Based on the law of conservation of energy, which statement is correct?

D. Energy in an isolated system remains constant

General Formulas and Concepts:

Physics

Explanation:

According to the Law of Conservation of Energy, it cannot be created or destroyed.

Therefore, we can eliminate choices A and B right off the bat.

We need to choose between C and D. We know that even though energy cannot be created or destroyed, it can be changed into a different form. Therefore, the correct answer is D.

6/12=1/2

step-by-step explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
