### Matching Section
# Brief Explanations:
Each term is matched to its definition/description based on static electricity concepts:
1. Conduction matches electron transfer via direct contact.
2. Static discharge matches the doorknob shock and lightning as examples.
3. Conservation of charge states charges are not created/destroyed.
4. Static electricity is the buildup of charge on an object.
5. Electric field is the area around a charged object.
6. Lightning is an example of electric discharge.
7. Friction is how socks in a dryer build charge.
8. Induction is electron movement from a nearby charged object.
9. Electric Force is the attraction between the coke can and plastic bat.
# Answer:
1. Conduction → The transfer of electrons through the direct contact
2. Static discharge → An example of this is when you get a shock from a doorknob
3. Conservation of charge → This states that that charges are not created or destroyed.
4. Static electricity → When you have a build up of charges on an object.
5. Electric field → The area around an object that the charges extend.
6. Lightning → This is an example of electric discharge.
7. Friction → Socks in the dryer build up charges through this process.
8. Induction → The movement of electrons from one part of an object to another because of the presence another charged object.
9. Electric Force → This was demonstrated when the coke can was attracted to the plastic bat and rolled with it.

### Explanation 1: Walking on Carpet + Doorknob Shock
# Brief Explanations:
The process uses friction, static electricity, and static discharge:
1. **Friction**: Walking across a carpet transfers electrons between your shoes and the carpet, giving your body a net static charge (static electricity).
2. **Static Electricity**: Your body holds this excess charge, creating a potential difference with the neutral doorknob.
3. **Static Discharge**: When you touch the conductive doorknob, the excess electrons rapidly transfer from your body to the doorknob, creating the visible/feeling shock.
# Answer:
When you walk across a carpet, **friction** between your shoes and the carpet transfers electrons, leaving your body with a net static charge (this buildup is **static electricity**). The neutral metal doorknob acts as a conductor; when you touch it, the excess charge on your body rapidly transfers to the doorknob in a **static discharge**, which is the shock you feel.

### Explanation 2: Lightning Formation Conditions
# Brief Explanations:
Lightning relies on charge separation, electric fields, and static discharge in clouds:
1. **Charge Separation**: In a storm cloud, updrafts carry ice crystals upward, and downdrafts carry hailstones downward. Collisions transfer electrons, making the bottom of the cloud negatively charged and the top positively charged.
2. **Electric Field**: The negative cloud bottom induces a positive charge on the ground below, creating a strong electric field between the cloud and ground.
3. **Static Discharge**: When the electric field is strong enough to ionize the air (turn it into a conductive plasma), a channel of charge forms. Electrons rush from the cloud to the ground, creating the visible lightning strike (a large-scale **static discharge**).
# Answer:
Lightning forms when storm clouds undergo **charge separation**: updrafts carry small ice crystals upward, while downdrafts carry heavy hailstones downward. Collisions between these particles transfer electrons, leaving the bottom of the cloud with a net negative charge and the ground below induced with a positive charge. This creates an extremely strong **electric field** between the cloud and ground. When the field is powerful enough to ionize the air (making it conductive), a rapid **static discharge** occurs: electrons flow from the cloud to the ground, producing the visible lightning strike.

### Charge Combinations (Law of Electric Charges)
# Brief Explanations:
The law of electric charges states: opposite charges attract, like charges repel. Arrows indicate attraction (toward each other) or repulsion (away from each other).
# Answer:
1. Left diagram (arrows pointing toward each other, attraction): $\boldsymbol{+}$ and $\boldsymbol{-}$
2. Middle diagram (arrows pointing away from each other, repulsion): $\boldsymbol{+}$ and $\boldsymbol{+}$ (or $\boldsymbol{-}$ and $\boldsymbol{-}$)
3. Right diagram (arrows pointing away from each other, repulsion): $\boldsymbol{-}$ and $\boldsymbol{-}$ (or $\boldsymbol{+}$ and $\boldsymbol{+}$)
