Electric Force

Front

What is electric force?

Back

Electric force is the attraction or repulsion between charged objects, governed by Coulomb's law.

Front

What happens to a positively charged particle in the presence of a negatively charged object?

Back

The positively charged particle will move toward the negatively charged object due to the attractive electric force.

Front

What is potential energy in the context of electric charges?

Back

Potential energy is the energy stored due to the position of charged objects relative to each other.

Front

What occurs to the potential energy when two oppositely charged objects are moved apart?

Back

The potential energy between the objects increases as they are moved apart.

Front

What is the principle behind charging an object by friction?

Back

Charging by friction occurs when two different materials are rubbed together, causing electrons to transfer from one material to another.

Front

What is induction in the context of electric charge?

Back

Induction is the process by which a charged object can induce a charge in a nearby neutral object without direct contact.

Front

What is polarization in terms of electric charge?

Back

Polarization is the separation of charges within an object, causing one side to become more positive and the other more negative.

Front

How do electric fields affect charged particles?

Back

Electric fields exert forces on charged particles, causing them to move toward or away from other charges.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charge to flow freely due to the presence of free-moving charged particles, while insulators do not.

Front

Why are conductors better than insulators for carrying electric current?

Back

Conductors have negatively charged particles that flow more freely, resulting in less resistance to the flow of charge.
