What are the differences between charging by contact and charging by induction?
Contact: Requires direct touch, results in the same charge. | Induction: No direct touch, results in opposite charge.
What are the differences between conductors and insulators in the context of charging?
Conductors: Allow charges to move freely. | Insulators: Resist the movement of charges.
What are the differences between positive and negative charges?
Positive: Deficiency of electrons. | Negative: Excess of electrons.
What are the differences between attractive and repulsive electric forces?
Attractive: Occurs between opposite charges. | Repulsive: Occurs between like charges.
What are the differences between charge transfer and charge creation?
Charge Transfer: Movement of existing charges from one object to another. | Charge Creation: Hypothetical process that does not occur in normal electrostatic interactions (violates conservation of charge).
What are the differences between charging by contact and charging by induction?
Contact: Requires direct touch, transfers charge | Induction: No direct touch, causes charge separation and may require grounding.
Compare and contrast conductors and insulators in the context of charging.
Conductors: Allow charges to move freely | Insulators: Resist the movement of charges.
What are the key differences between attraction and repulsion in electrostatics?
Attraction: Occurs between opposite charges | Repulsion: Occurs between like charges.
What are the differences between charging by friction and induced charge separation?
Friction: Requires rubbing and direct contact, results in net charge on both objects | Induced Charge Separation: No direct contact, results in temporary charge polarization without a net charge.
Compare the effects of grounding a positively charged object versus a negatively charged object.
Positively Charged: Electrons flow from the ground to the object, neutralizing it | Negatively Charged: Electrons flow from the object to the ground, neutralizing it.
Define 'charging' in electrostatics.
Charging is the process of redistributing electrons between objects, not creating charge.
What is 'conservation of charge'?
The total charge in an isolated system remains constant; charge is neither created nor destroyed, only transferred.
Define 'grounding'.
Connecting a charged object to the Earth, allowing excess charge to flow away and neutralize the object.
What is 'induced charge separation'?
Bringing a charged object near a neutral one, causing the charges within the neutral object to shift, creating a polarized object without direct contact.
Define 'electric force'.
The attractive or repulsive force between charged objects, governed by Coulomb's Law.
