| What charges do Atoms contain? | Positive charges [Protons] and Negative Charges [Electron] |
| What is Neutral Matter | This is where the number of Positive Charge is the Same as the Number of Negative Charge [Protons = Electrons] |
| What happens when 2 materials rub together?
What happens if 2 Insulators and Conductors rub together? | -The Electrons will be Transferred from One to the Other
-In the Conductor, The Electrons will just flow back into or out, making them Neutral
-In the Insulators, The Electrons can not flow meaning a Positive Charge will be left on the Object that lost Electrons, and the Negative Charge will be applied on the Other Object, because it has Gained Electrons. |
| Can Protons move? or Just Electrons | Only Electrons can move. Not Protons |
| What happens if enough Charge is present on a Object? | -It can Move, which will cause Sparks and Shocks |
| What do Electrically Charged Objects Exert? | They exert a Force with one another. This force gets Weaker over Distance however |
| What happens if 2 Objects had:
a] Same Charge
b] Opposite Charge | -If two objects has the Same Charge, they would repel against Each other
-If two objects has the Opposite Charge, they would Attract each other |
| What is Electrostatic Attraction and Electrostatic Repulsion? | This is the Force that Attracts 2 Charged Objects
OR
The force that Repels 2 Charged Objects
[This force is Non-Contact] |
| So what will happen if you put 2 same charges Rod next to each other? | They will both repel each-other. Simple as that |
| Using a Charge Rod and some Scraps of Paper, what will happen? and Why? | -The Small papers will try to Jump towards the Rod
-This is because the Rod will push the Electrons away [Negative Charged] or pull the Electrons [Positively Charged] towards the Rod
-Remember, Protons can not be moved, so if it was a Negative Charge, the Electrons would repel away [go to the Other side of the Paper] |
| Using a Stream of Water [Vertical], how can you test a Charged Object? | -The Charged Object will affect the Stream of water by Bending it Towards or Away. |
| Using the Gold leaf Electroscopes, how can you test a Charged Objected | -If a Negative Charged Object touches the Zinc Plate, the Electrons or Charge will be taken towards the Electroscope, into the Metal Stem and Gold leaf [Conducted into]
-This makes the Stem and Gold Leaf rise, Same Charge Repels so the Gold leaf will rise
-Use a Positive Charged Object, Electrons repel from the Zinc Plate, towards the Stem and Gold Leaf, Charging them with the Same Charge, the Leaf will rise |
