What does the law of conservation of energy state? * 1. Total energy before transfer is equal to total energy after transfer

2. Total energy before transfer is less than total energy after transfer

3. Total energy before transfer is more than total energy after transfer

total energy before transfer is equal to total energy after transfer

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.
