Definition of Electricity
the presence and/or flow of electric charges
What's the definition of energy?
Means the ability to work
If an astronaut throws a ball in space, when will the ball stop?
The ball won't stop
What are the four familiar states of matter?
Solid,Liquid,Gas, and Plasma
Definition of a wave
a disturbance that carries energy from one location to another location.
Higher Current=
Faster Moving Electric Charges (Electrons)
What's the SI unit of energy?
(J) Joules
What is a measure of inertia?
Mass
Examples of heterogeneous mixture
Chocolate Chip Cookies
All waves must have what to travel?

Voltage
is the potential difference between two points in a circuit
Examples of potential energy
a drawn bow, a car on top of a hill
Which of Newton's laws states that for every action there is an equal and opposite reaction?
Newton's Third Law of Motion
Examples of homogeneous mixtures
Salt water, Sugar Water
What direction does a transverse wave move?
Perpendicular
Example of electrical energy changing to other forms of energy

What term is to describe changing from Liquid to a gas?
Vaporization
Where are the crest and trough of the wave
Crest= top of the wave
Trough=bottom of the wave
Electric Charge
Objects become positively charged when they lose electrons and negatively charged when they gain electrons; objects with like charges repel and objects with opposite charges attract.
The law of conversation of energy...?
states that the total amount of energy in a system remains constant or conserved.
Which of Newton's laws explain inertia?
Newton's First Law of Motion
What is a Universal Solvent?
Water
Longitudinal wave
A wave that has the motion of the medium parallel to the direction of the wave.
