Chapter 3 - Electric Force, Field, and Potential

Net force

Net force

The ________ on any charge inside a conducting sphere is 0.

metals

Generally, ________ are good conductors and nonmetals are insulators.

Quanta

________ is the smallest package of a proton or electron that charge comes in.

static electricity

Electrons are easier to remove and in ________, we assume only electrons are being removed /added.

Zero

________ of electric potential=ground = a theoretical distance at which two charged particles are infinitely far away from each other and therefore don’t affect each other.

K

________ is the dielectric constant which shows how good of an insulator you have between plates.

ΔV

_____ is the magnitude of the voltage difference between plates.

electric field

Inside a conducting sphere, the ________ is 0.

Parallel plates

________ can be used to make capacitors (a device that stores charges and will be further explored in circuits)

negative charge

The direction of the force on a(n) ________ is the opposite direction as the electric field.

Electric potential

________ is scalar (only have magnitudes)

E

________ is the magnitude of the electric field.

protons

When an object has more electrons than ________, its negatively charged.

Law of conservation of charge

The _____________ states that the initial charge of the system will always equal the final charge of the system

Conductors

__________ allow charge to move easily through them

Insulators

____________ don’t allow charge to move easily through them (held in place)

Charging by Friction

______________ is accomplished by rubbing two objects like a fuzzy towel and iron rod, resulting in electrons jumping from one object to the other

Induced charge

An _________ is created when a neutrally charged object becomes polarized (electrons clump up on one side of the object and positive charges pile on the other side)

Field

A __________ is a property of a region that can apply force to objects found in that space

Electric potential

____________ is the Electric potential energy per unit charge (provided by an electric field)

Equipotential lines

______________ are lines on which a charged particle would have the same potential
