Question

detecting charge - electroscope: tool used to detect the presence and ____ of an __ materials conductors: materials that allow e⁻ to __ __; readily __ electric charge - ex. __ (especially copper in wires) and __ insulators: materials that __ of e⁻ through them - ex. plastic, __, air, __, and glass transfer of charge 1. conduction: transfer of electrons through __ between objects - __ from one object __ to another object - object must be a __ to transfer the __ 2. friction: transfer of electrons through __ - ex. socks rubbing on __, then touching your sibling and __ them 3. induction: transfer of electrons through __ working over a __ - charged object is brought near a __ object, causing ____ and inducing a charge on the neutral object

Explanation:

• Electroscope: It is a tool used to detect the presence and type of an electric charge.
• Conductors: Materials that allow electrons to move freely and readily transfer electric charge. Examples include metals (especially copper in wires) and aluminum.
• Insulators: Materials that do not allow electrons to move freely through them. Examples include plastic, rubber, air, wood, and glass.
• Conduction: Transfer of electrons through direct contact between objects. Electrons move from one object to another. The object must be a conductor to transfer the charge.
• Friction: Transfer of electrons through rubbing. For example, socks rubbing on carpet, then touching your sibling and shocking them.
• Induction: Transfer of electrons through working over a distance. A charged object is brought near a neutral object, causing polarization and inducing a charge on the neutral object.

Answer:

• Electroscope: type, electric charge
• Conductors: move, freely, transfer, metals, aluminum
• Insulators: do not allow electrons to move, rubber, wood
• Conduction: direct contact, Electrons, move, conductor, charge
• Friction: rubbing, carpet, shocking
• Induction: distance, neutral, polarization
