Untitled Flashcards Set

Electric Force

A field force that acts at a distance between charged objects.

Polarization

Redistribution of charge in an object due to a nearby charged object.

Coulomb's Law

States that electric force is directly proportional to the product of charges and inversely proportional to the square of the distance between them.

Electric Potential Energy

Energy due to position in an electric field.

Electric Current

The rate of flow of electric charge, measured in amperes.

Ohm's Law

V = IR, defining the relationship between voltage, current, and resistance.

Resistance

Opposition to the flow of electric current, measured in ohms (Ω).

Series Circuit

A circuit in which the current is the same at all points.

Parallel Circuit

A circuit in which voltage remains the same across all branches.

Short Circuit

A circuit that presents little resistance and can lead to overheating.

Electric Field Strength

Measured in Newtons per Coulomb (N/C), represents the force experienced by a charge in an electric field.

Magnetic Domains

Groups of aligned atomic spins that create magnetic properties.

Frequency

The number of oscillations or cycles per second, measured in Hertz (Hz).

Doppler Effect

Change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Resonance

When an object vibrates at its natural frequency due to an external force.

Total Internal Reflection

When light reflects completely back into a denser medium beyond a critical angle.

Dispersion

The separation of light into colors based on wavelength.

Converging Lens

A type of lens that brings light rays together to a focus.

Virtual Image

An image formed by rays that appear to diverge from a point but do not actually converge.

Specular Reflection

Reflection of light from a smooth surface, producing clear images.
