energy
Radiation
The transfer of thermal energy from one material by electromagnetic waves.
Hypothesis
An explanation that is based on prior scientific research or observations and that can be tested.
Medium
Material through which a wave travels
distance
how far an object has moved
static electricity
stationary electric charge that is caused by two objects rubbing electrons off each other.
Convection
The transfer of thermal energy by the movement of particles from one part of a material to another
Table
A structured format containing columns and rows to hold a collection of related data.
Compressional Wave
Matter in the medium moves back and forth along the same direction that the wave travels
average speed
total distance traveled divided by the amount of time traveled
lightning
huge static electric discharge
kinetic energy
energy that an object has due to its motion
SI System
The International System of Units is the modern form of the metric system, and is the most widely used system of measurement. It comprises a coherent system of units of measurement built on seven base units.
Wave period
How long it takes a wave to pass a point.
velocity
the speed of an object and the direction of its motion
current electricity
electrons flowing through a wire to complete a circuit
nuclear energy
the potential energy stored in the nucleus of an atom
Volume
A measure of the size of a body or region in three-dimensional space.
Wave Interference
Occurs when two or more waves meet while traveling along the same medium.
acceleration
the rate of change of velocity
circuit
a path for electrons to flow through a wire, it must be closed in order for the electricity to work
law of conservation of energy
the rule that energy cannot be created or destroyed
Scientific Method
A series of steps followed to solve problems.
Intensity
The amount of energy that flows through a certain area in a specific amount of time
Force
push or pull on an object
Generator
a machine that usually uses steam to spin a rotor with a magnet within a coil of wire to produce electricity
