1- charging by touch occurs when electrons are transmitted by direct contact. (Right)
(wrong)

2- Electric charges are preserved, they are not created or destroyed.
(Right)
(wrong)​

#1 - True (touch) charging when electric conductors actually touch one another.

#2. True - electrical charges are conserved (not destroyed)

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.
