| Electric charge that accumulates on an object and remains stationary. | Static Charge |
| What is static charge? | Static charge is electric charge that accumulates on an object and remains stationary. |
| Materials that do not allow the easy flow of electric charge. | Insulating Materials. |
| What type of materials can become electrically charged through friction? | Insulating Materials. |
| The process of generating static charge by rubbing insulating materials together, causing electrons to transfer between them. | Friction-Induced Charging |
| How is static charge generated through friction? | Friction-induced charging occurs when insulating materials are rubbed together, causing electrons to transfer between them. |
| Electrons move from one material to another during friction-induced charging. | Electron Jumping |
| What occurs when insulating materials are rubbed together during friction-induced charging? | Electrons jump from one material to another. |
| After friction-induced charging, the two materials involved have an equal and opposite charge. | Charge Distribution |
| How is charge distributed between two materials involved in friction-induced charging? | The two materials have an equal and opposite charge. |
| Electrons have a negative charge. | Electron Charge |
| What is the charge of electrons? | Electrons have a negative charge. |
| The material that gains electrons becomes negatively charged, and the material that loses electrons becomes positively charged. | Positive and Negative Charging |
| How are materials charged during friction-induced charging? | The material that gains electrons becomes negatively charged, and the material that loses electrons becomes positively charged. |
| Because insulators do not allow easy electron movement, objects made of insulating materials retain their static charge. | Insulators and Electron Movement |
| Why do objects made of insulating materials retain their static charge? | Because insulators do not allow easy electron movement. |
| Objects involved in friction-induced charging, being insulators, do not easily lose their static charge. | Remain Charged |
| Why do objects involved in friction-induced charging, especially insulators, remain charged? | Because insulators do not easily lose their static charge. |
| Forces exerted between electrically charged objects. | Electric Forces |
| What are electric forces? | Electric forces are forces exerted between electrically charged objects. |
| Objects with the same type of charge (both positive or both negative). | Like Charges |
| How do objects with like charges interact? | Objects with like charges repel each other. |
| The force that pushes objects with like charges away from each other. | Repulsion |
| What is repulsion in the context of electric forces? | Repulsion is the force that pushes objects with like charges away from each other. |
| Objects with different types of charge (one positive and one negative). | Opposite Charges |
| How do objects with opposite charges interact? | Objects with opposite charges attract each other. |
| The force that pulls objects with opposite charges toward each other. | Attraction |
| What is attraction in the context of electric forces? | Attraction is the force that pulls objects with opposite charges toward each other. |
| Forces that do not require objects to be physically touching. | Non-Contact Forces |
| Are electric forces examples of contact or non-contact forces? | Electric forces are examples of non-contact forces. |
| Hanging a charged rod from a thread to observe its interaction with other charged objects. | Demonstrating Electric Forces |
| How can electric forces be demonstrated using a charged rod? | Hanging a charged rod from a thread and observing its interaction with other charged objects. |
| If a charged rod is attracted to another charged object, they have opposite charges. | Opposite Charges Interaction |
| What does it indicate if a charged rod is attracted to another charged object? | They have opposite charges. |
| If a charged rod is repelled by another charged object, they have like charges. | Like Charges Interaction |
| What does it indicate if a charged rod is repelled by another charged object? | They have like charges. |
