and simply click Run At this point.
1 . You rub balloons in your curly hair and then hold them similar to the picture below. Explain how come you think they will move separate and what might have an effect on how far aside they obtain. When the balloons are rubbing together they can be taking charges(electrons ) in one another. Once rubbed against your hair, the balloon take electrons from the hair getting out of the relationship hair great. You locks will then turn into attracted to the ballon because you frizzy hair is efficiently charged and the balloon adversely charged. You hair will certainly stand up even if the go up is not close to you because each hair is great and repelled by the additional positive hairs.
2 . Test your ideas employing Electric Field Hockey in the Practice setting. Make a table to record the observations by what affects the direction and speed from the puck. The table should certainly demonstrate that you have got run controlled tests considering the variables. The puck is usually affected by just how close the charges are to this and what the puck's impose is. For example if the puck is confident the positive fees are repelled; the arrow grows much longer and away from the puck because the positive charges move nearer to the puck. IF the puck is great and the expenses are negative, the arrow grows much larger as the negative costs move better and points toward the charge.
three or more. Reflect on your opinions from query #1 plus your data via question #2. How do the observations support, dispute or add to your concepts about what affects how recharged bodies communicate? My findings support my ideas via question 1 . After trying out the puck and charges I was able to see how the fees affect the puck by either repelled or perhaps attracting this to the fees.
4. As you put charges onto the playing location, arrows appear on the puck....
