You rub balloons in your hair and whence hang them like in the picture below. Explain why you deal they move apart and what might affect how far apart they get. A balloon becomes negatively debased when it is rubbed on a persons hair.This occurs because all the protons and neutrons leave the balloon and attach to other objects such as the hair. If two balloons both have negative charges then both balloons leave repel each other because same charges repel while opposites attract. 2. shield your ideas using Electric Field Hockey in the Practice mode. catch a prorogue to record your observations about what affects the direction and reanimate of the puck. Your table should demonstrate that you have run controlled tests with all the variables. Charges introduced do on positive(p) charge distaste Positive Repel Neg ative Attract Charges introduced Effects on positive charge speed Positive Close to charge=Increasing repulsion speed Far from charge= decreasing repulsion speed Negative Close to charge=Increasing attraction speed Far from charge= decreasing attraction speed 3. Reflect on your ideas from question 1 and your data from question 2. How do your observations shop at, dispute or add to your ideas about what affects how supercharged bodies interact? The data collected helps support my claims that like charges repel each other while opposites attract. In the slipperiness of the balloons both balloons are negative there for repelling each other. 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?The arrows illustrate the movement of the pucks as well as velocity. How do the arrows from the positive charges compare and contrast to the ones from the negative balls? The positive charges bet to re pel the puck while the negatives attract. Investigate how you can use the arrows to name the motion of the puck. 5. Write an explanation of how you can predict the motion of a charged hockey puck that is moved by other charged pucks. Explain using examples and drawings that include How to use free body diagrams and vector addition. How negative and positive charges compare and contrast.
