The amplitude of a periodic variable is a measure of its change over a single period
Amplitude
300
a part or aspect of something abstract, especially one that is essential or characteristic
Element
300
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Conduction
300
an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
Gas
300
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

Crest
400
having no strongly marked or positive characteristics or features
Neutral
400

Conservation of energy
400
a plane inclined at an angle to the horizontal
Inclined plane

Diffraction
500
The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton
Neutron
500
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Convection
500
the exertion of force by means of a lever or an object used in the manner of a lever.
Lever
500
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
