Circuits
The flow of charged particles
What is an electric current?
states that for
every action, there is an equal and
opposite reaction.
What is Newtons 3rd law
is the energy of motion.
What is kinetic energy?
a disturbance that
carries energy from one
location to another location.
What is a wave?
Joules ( J)
What is the Si unit for energy
Faster Moving Electric Charges (Electrons)
What is in a higher current?
if only gravity
acts on it.
When does an object free fall
is matter that has a definite volume
but no definite shape.
What is a liquid?
energy
and NOT matter!
What do waves transport?
is the energy
stored in elastic materials as the result of
their stretching or compressing.
What is Elastic Potential Energy?
electrons to flow from
a negative pole (excess electrons) to a positive
pole (deficient in electrons)
Where do electrons flow?
Fluid friction (a.k.a. air resistance)
What slows acceleration?
greater average
kinetic energy, so most substances expand
when heated.
What does increased temperature mean?
Transverse waves and
Longitudinal waves
What are the two types of mechanical Waves?
potential energy or kinetic energy.
What are the 2 types of energy?
an energy source, wires, and the object that is going to change the electrical energy into another form of energy (load).
What are the 3 things needed in electric circuits?
the measure of an object’s change in
position from start to end
What is displacement?
Are packed tightly together and can only
vibrate.
How are the particles in a solid?
medium moves
in a direction perpendicular to the
direction that the wave moves.
What is a transverse wave?
Energy cannot be created or
destroyed, but it can be transformed.
What does the law of conservation of energy say?
Changes electrical energy to other
forms of energy
What is a load?
states that the net
force is equal to the acceleration times
the mass of the object (F=ma).
What is Newtons 2nd Law?
in fluorescent light bulbs and Neon
lights.
Where is plasma used?
is how much energy
the wave carries. It is the distance
from rest to crest or rest to trough.
What is the amiplitude?
energy from fossil
fuels (crude oil, coal, natural gas) and uranium
(nuclear energy).
What is nonrenewable energy?
