Activity 1
Charged interactions
Objectives
After performing this activity, you should be able to:
1. charge a material by friction;
2. observe the behavior of charged objects;
3. distinguish between the two types of charges; and
4. demonstrate how objects can be discharged.
Materials Needed:
Strong adhesive tape (transparent)
Procedure:
1. Using a meter stick, pull off a 40- to 60- cm piece of adhesive tape and fold
a short section of it (~1 cm) to make a nonsticky "handle" at that end of the
tape.
2. Lay the tape adhesive side down and slide your finger along the tape to
firmly attach it to a smooth, dry surface of a table.
3. Peel the tape from the surface vigorously pulling up on the handle you have
made on one end. See figure below. Make sure that the tape does not curl
up around itself or your fingers.
4. While holding the tape up by the handle and away from other objects,
attach the tape to the horizontal wooden piece or the edge of your table.
Make sure that the sticky side does not come in contact with other objects.
