What is the rate of change in velocity, usually expressed in meters per second; involves an increase or decrease in speed and/or a change in direction
100
atom
What is the smallest unit of a chemical element that can still retain
the properties of that element
100
Calorie
What is the energy needed to raise the temperature of 1 gram of water through 1 °C (now usually defined as 4.1868 joules).
100
Change of state
What is CHANGING STATES. All matter exists as solids, liquids, or gases. ... Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water
100
Dependent Variable
What is a variable (often denoted by y ) whose value depends on that of another.
200
air resistance
What is force of air on moving objects
200
electron
What is a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
200
Condensation
What is water that collects as droplets on a cold surface when humid air is in contact with it.
200
Chemical change
What is Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
200
Independent variable
What is a variable (often denoted by x ) whose variation does not depend on that of another.
300
amplitude
What is in any periodic function (e.g., a wave) the maximum
absolute variation of the function
300
element
What is a part or aspect of something abstract, especially one that is essential or characteristic.
300
Conduction
What is 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.
300
Circuit
What is a roughly circular line, route, or movement that starts and finishes at the same place.
300
Experiment
What is a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
400
crest
What is the peak or highest point on a wave
400
Neutral
What is Belonging to neither kind
400
Conservation of energy
What is a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
400
Compound
What is a thing that is composed of two or more separate elements; a mixture
400
Investigation
What is the action of investigating something or someone; formal or systematic examination or research.
500
diffraction
What is the change in direction of a wave caused by passing by an
obstacle or traveling through an opening
500
Proton
What is Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons".
500
Convection
What is 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.
500
Density
What is the degree of compactness of a substance.
500
Variable
What is not consistent or having a fixed pattern; liable to change.
