Defining Characteristics of the Electric Charge Interaction
Before performing today's lab, we made a hypothesis:
When the charged object (balloon) is held above the nonmetal materials, (paper) the pieces will attract and attach themselves to the balloon. When we hold the charged object above metal material, it won't attract.
Summary: We found that when the balloon was charged it picked up both the paper and the aluminum foil. We also found that when we held two charged balloons next to each other they repelled on one side and they attracted on another. (Parker)Are there any other conditions that have to be met? Touching, near each other, etc.?? [2 - Almost there] Procedure: (Aveleka)
1. Blow up balloon
2. Rub balloon with silk cloth
3. Hold tail of balloon on top of non-metal materials
4. Record
5. Take off anything stuck to balloon
6. Re-rub balloon with silk cloth
7. Hold tail of balloon on top of metal materials
8. Record What about the two balloons? What were the metal and non-metal materials we used? How did we prepare them? Are there metals that are not magnetic material? Does this make a difference? Your procedure is not very thorough. [1 - On your way]
Circumstances under which the electrical charge interactions occur: (Sami)Were you absent or was homework incomplete?
Results: (Anthony)
-Non-magnetic material: The non magnetic material was attracted to the balloon I know this happened because there was a change in motion with the paper shreds.
-Magnetic material: The magnetic materials were also attracted to the charge created by the balloon and just like the paper shreds there was a change in motion as the foil was attracted to the balloon.
-Two charged objects: The two charged objects like two magnets with the same charge pushed away from each other this can also be proven through a change in motion. Did you PROVE it?
