1.
1st Law of Motion: Matter tends to stay at rest or in motion unless acted on by an outside force
2.
2nd Law of Motion: A change in motion depends on the mass, or the amount of matter in an object and the amount of force acting on the object
3.
3rd Law of Motion: for every action there is an equal but opposite reaction force
4.
amplitude: is the distance a wave rises or fulls from its resting positions
5.
atoms: the building block of matter
6.
attract: to pull together
7.
circuit: path for electric current
8.
circuit breakers: is a switch that turns off whenever too much electricity flow through it
9.
conductor: material through which heat travels easily; material through which electricity passes easily
10.
crest: top of a wave
11.
Electric current: movement of electrons from one place to another
12.
Electricity: flowof electrons
13.
Electromagnetic: temporary magnet made by passing a current through a wire wrapped around an iron core
14.
electrons: a tiny particle of an atom that moves around the nucleus
15.
Energy: is the ability to do work
16.
Force: is the push or pull that moves something
17.
fuse: is a small strip of metal designed to burn out if too much electricity flows through it
18.
Inclined plane: simple machine made up of a ramp, used to lift an object
19.
Inertia: tendency of an object to resist changes in its motion
20.
Insulator: a material that does not conduct heat well; material through which electricity does not pass easily
21.
light and sound: are types of energy that travel as waves from one place to another
22.
Machine: is anything that makes work easier
23.
magnetic field: area around a magnet in which magnetic forces can act
24.
magnetic poles: opposite points or ends of magnet, where magnetic forces are greatest
25.
Matter: is anything that takes up space
26.
Physics: is the branch of science that studies matter and energy and the relationship between them
27.
prism: a piece of glass or plastic that is shaped like a triangle and can be used to separate white light
28.
reflected: light doesn't pass through
29.
repel: push away
30.
simple machines: such as crowbars and screwdrivers, tools that makes work easier
31.
Thomas Edison: built the first electric power station in NYC
32.
transparent: light goes through easily
33.
trough: bottom or lowest point of a wave
34.
vibrate: to move rapidly back forth
35.
wave: is a periodic disturbance that carries energy from point to point through space or matter
36.
wavelength: is the distance between waves
37.
white light: mixture of difference colors of light
