1. You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get.
As I rub the balloons in my hair, I am picking up positive charges from my hair, which are electrons. The static charge produced will remain active on the balloons, so when they are stuck to the wall by attraction, and then repel one another. Given that the fundamental laws of nature tells us that no charge can be created nor destroyed, I think of the balloons as holding two magnets with the same negative …show more content…
Reflect on your ideas from question #1 and your data from question #2. How do your observations support, dispute or add to your ideas about what affects how charged bodies interact?
The electric field hockey game is only supporting my earlier claimed in the first question, but in greater detail by visually seeing the dramatic results from the two different charges interacting in the game.
The more static charge a person has in their hair, the stronger the hold will be against the wall of the balloons will obtain, and the faster they will move apart from one another until some other material pulls those charges away; for example lubricant on the hand.
4. As you put charges onto the playing area, arrows appear on the puck.
What do you think the arrows on the puck are illustrating?
With the puck being positive, we know that like attract and positives repel, so the arrows would obviously predict the direction that the charged particle has on the puck.
How do the arrows from the positive charges compare and contrast to the ones from the negative balls?
They have an opposite affect or …show more content…
Demonstrated below, from the website:
How to use free body diagrams and vector addition.
The diagram can be used to demonstrate how and which forces are acting on the puck, if the square in the above example is used. It would help me to illustrate the forces / energy and directions they take and to help better predict the motion that the puck would take. You can also use, ‘vector addition’ to predict the path(s).
How negative and positive charges compare and contrast.
If dealing with multiple pucks (opposite charges/ force), they will attract to one another. If there is a puck with a much greater number of (+) ions, the directions on the playing field will move more quickly, but if the low number of charges is the same, the affects will be minimal. Attraction and repulsion occur depending on the charge possessed by the puck. It also depends on how much friction is on the field, the pucks could move more freely about, and one might see a spinning path when the puck come in close proximity to one another with opposite charges. One could imagine a bohr model of an electron going around a
