STATIC ELECTRICTY

CHARGE BY FRICTION, CONDUCTION, INDUCTION I. Friction Gliding across carpet can build up charge. Rubbing Wool across a glass rod can build up charge. II. Conduction Two objects (one charged another neutral). When they touch the charge from the charged object moves to the neutral object. III. Induction A charged balloon brought near pieces of neutral paper without touching. The paper will jump up to the balloon.

TRANSFER OF CHARGE Directions: Copy the following statements. Identify the statement as induction, conduction, or friction. Lightning in the air and then touches the ground. Lightning in the air and then touches the ground. A wool sweater is cling to a silk tie. A wool sweater is cling to a silk tie. If you hold a negatively charges plastic rod up to a ball hanging on a thread and the ball moves away from the rod.
