A particle, object, or system that lacks a net charge.
What is Neutral?
100
The process of changing from a gas (i.e., water vapor) to a
liquid (i.e., dew); the act of making more dense or compact.
What is Condensation?
100
A physical change that occurs when matter changes to
another state (i.e., liquid, gas, or solid).
What is Change of state?
100
Factor being measured or observed in an experiment.
What is Dependent Variable?
200
In any periodic function (e.g., a wave) the maximum absolute variation of the function.
What is Amplitude?
200
A force of attraction between two masses.
What is Gravitation?
200
The transmission of heat through a medium and without the
motion of the medium.
What is Conduction?
200
A reaction or a change in a substance produced by
chemical means that results in producing a different
chemical.
What is Chemical change?
200
The factor that is changed in an experiment in order to study
changes in the dependent variable.
What is Independent variable?
300
The change in direction of a wave caused by passing by an
obstacle or traveling through an opening.
What is Diffraction?
300
The property of an object, due to its mass, that causes it to
resist any change in its motion unless overcome by a force.
What is Inertia?
300
A fundamental principle stating energy cannot be created
nor destroyed but only changed from one form to another.
What is Conservation of energy?
300
An interconnection of electrical elements forming a
complete path for the flow of current.
What is Circuit?
400
The number of cycles or waves per unit time.
What is Frequency?
400
The lowest point on a wave.
What is Trough?
400
Heat transfer in a gas or liquid by the circulation of currents
from one region to another.
What is Convection?
400
Concentration of matter of an object; number of individuals
in the same species that live in a given area; the mass per
unit volume of a substance in a given area.
What is Density?
400
A change of energy from one form to another (e.g.,
mechanical to electrical, solar to electrical).
What is Energy transfer?
500
A force that opposes the relative motion of two material
surfaces in contact with one another.
What is Friction?
500
The time-rate at which a body changes its position; defined
as displacement divided by the time of travel.
What is Velocity?
500
The emission and propagation of the entire range of the
electromagnetic spectrum including: gamma rays, x-rays,
ultraviolet radiation, visible light, microwaves, and radio
waves.
What is Electromagnetic Radiation?
500
The pivot point of a lever.
What is Fulcrum?
500
A measure of randomness or disorder of a closed system.
