100

The rate of change of position (distance per time or d/t).

What is speed?

100
The accumulation of excess charge on an object.
What is static electricity?
100
The medium moves back and forth in the same direction the wave travels like sound waves.
What is a compressional wave?
100
Particles are far apart and have no definite shape or volume.
What are gases?
100

Negatively charged atomic particles that orbit the nucleus like bees swarm their hive.

What is an electron?

200

Speed with direction.

What is velocity?

200
The flow of charges through wire or any conductor.
What is electric current?
200
The less dense region of a compressional wave.
What is rarefaction?
200
Explains how lift helps airplanes fly.
What is Bernoulli's Principle?
200
Mass Number - Atomic Number
What is the number of neutrons in an atom?
300
The rate of change of velocity (velocity per time)
What is acceleration?
300
V=IR
What is Ohm's Law?
300
The distance between one point on a wave and the nearest point just like it.
What is wavelength?
300
As temperature increases, volume also increases like with a hot air balloon.
What is Charles's Law?
300
Added to the end of the name of a binary compound.
What is -ide?
400
A push or a pull.
What is force?
400
A material that allows electrons to move easily through it.
What is electrical conductor?
400
When a wave strikes an object and bounces off it.
What is reflection?
400
A mixture in which two or more substances are blended evenly throughout.
What is a homogeneous mixture?
400

One substance breaks down or decomposes into two or more substances 2H2O→2H2+O2

What is a decomposition reaction?

500
Quantity of matter.
What is mass?
500
Contains two or more branches for current to move through like our houses do.
What is a parallel circuit?
500
Vibrating electric charges that can travel through space where no matter is present.
What are electromagnetic waves?
500
A heterogeneous mixture that suspends light like fog.
What is a colloid?
500
Energy given off in a chemical reaction is primarily in the form of HEAT.
What is an exothermic reaction?
