Gravitational and Electrostatic Forces Study Review
charge - -May be positive, negative, or neutral;
can be present on subatomic particles, atoms, or
molecules; causes the object to interact with
electromagnetic fields or other charged particles
Coulomb - -SI unit of charge; equal to the
quantity of electricity conveyed in one second by a
current of one ampere
Coulomb's Law - -A law describing the
electrostatic force of interaction between charged
particles based on the strength of the charges and
the distance between the particles
electric field - -A region around a charged
particle or object within which a force would be
exerted on other charged particles or objects
electrical force - -The interaction between a
charged particle and an electromagnetic field or
between two charged particles
electrostatic force - -A force created by the
interaction of stationary electric charges
field forces - -Forces that act over a distance,
such as gravity
gravitational field - -The region of space
surrounding a body in which another body
experiences a force of gravitational attraction
gravitational force - -A force of attraction
between two masses
law of universal gravitation - -The law stating
that every piece of matter is attracted to every other
piece of matter; the force is directly proportional to
their masses but inversely proportional to the square
of the distance between them
4 universal forces - -electromagnetic, strong
nuclear, weak nuclear, and gravitational
magnetic fields - -fields generated only by
moving charged objects and also magnets
weight - -A measure of the force of gravity on
an object
the closer the distance - -the stronger the
gravitational and electrostatic forces
Gravity (gravitation) - -A force of attraction
exerted by each particle of matter in the universe on
every other particle
the larger the mass - -the larger the force of
gravity
