circuits
the presence and/or flow
Electricity
a disturbance that carries energy from one location to another location.
Wave
matter that is always made up of the same combination of atoms.
Substances
Where is energy located
Energy is everywhere!
the rate in which you speed up, slow down, or change directions.
Acceleration
how difficult it is for electrons to flow through a material (friction).
Resistance
requires a medium in order to transport their energy.
Mechanical Waves
the 4 states of matter
solid, liquid,gas and plasma
is stored energy due to an object’s position--energy ready to go.
Potential energy
An object at rest remains at rest unless acted on by an unbalanced force.
Newtons 1st Law of Motion
the potential difference between two points in a circuit.
Voltage
medium moves in a direction perpendicular to the direction that the wave moves.
Transversal waves
A molecule with a slight negative charge in one area and a slight positive charge in another area.
Polar Molecule
Mechanical, Chemical, Nuclear, Solar, Thermal (Heat), Electrical, and Sound
Forms of Energy
states that the net force is equal to the acceleration times the mass of the object (F=ma).
Newtons 2nd Law of Motion
All circuits need three basic parts: an energy source, wires, and the object that is going to change the electrical energy into another form of energy (load).
TRUE !
A wave that has the motion of the medium parallel to the direction of the wave.
Longitudinal wave
matter composed of 2 or more elements in a fixed ratio
compound
Potential energy that is related to an object's height above the ground
Gravitational potential energy
states that for every action, there is an equal and opposite reaction.
Newtons 3rd Law of Motion
An electric circuit allows electrons to flow from a negative pole (excess electrons) to another negative pole (excess electrons)
FALSE! An electric circuit allows electrons to flow from a negative pole (excess electrons) to a positive pole (deficient in electrons)
are waves that are capable of traveling through a vacuum (empty space).
Electromagnetic waves
substances are not evenly distributed and they are easily separated.
Heterogeneous Mixture
a changing of one form of energy to another.
Energy conversion
has a single force that acts upon it - the force of gravity.
