Matter
This is made up of one type of atom.
What is an element?
The ability do to work or cause change.
What is Energy?
These forces are equal in size and opposite in direction.
What is balanced forces?
When a force is applied to an object and the object moves in the direction of the force.
What is work?
The accumulation of electric charges on an object.
What is static electricity?
The positive particle in an atom's nucleus.
What is a proton?
The molecules or atoms have very little molecular activity and are held or strongly influenced by the other molecules nearby.
What is a Solid?
This type of engine converts heat energy into mechanical energy.
What is a heat engine?
These forces always cause a change in motion.
What is unbalanced forces?
Simple machines make work easier by these three methods.
What is using a smaller force through a greater distance, by changing the direction of the force and change the effort needed.
Materials that allow electrons to flow.
What is a Conductor?
The sum of the protons and neutrons.
What is Atomic mass? or mass number?
A gas like mixture of charged particles.
What is plasma?
The speed of sound depends upon these two conditions.
What is the type of medium and the temperature?
How much force is needed to move a certain amount of matter. F=ma.
What is Newton's 2nd law of Motion?
The ratio of work output to work input.
What is efficiency?
A complete path that electrons can travel is called...
What is a circuit?
The periodic table is organized by this number.
What is the atomic number?
The measure of the amount of matter in a certain amount of space.
What is Density?
Energy cannot be created or destroyed but may change from one form to another.
What is the Law of Conservation of Energy?
This explains why boats move backwards as we step off and how a rocket flies.
What is Newton's 3rd law of Motion?
The rate at which work is done.
What is Power?
The tendency of a material to resist the flow of electrons.
What is Resistance?
These elements sit on the stair step or zigzag line. They are sometimes called semi-conductors.
What are the metalloids?
Compounds that contain carbon and usually hydrogen.

Water freezes at __ degrees Fahrenheit, _______ degrees Celsius and _________ Kelvin.
What is 32 degrees Fahrenheit, 0 degrees Celsius, and 273 Kelvin?
The force of attraction between two objects, causes free falling objects to accelerate.
What is gravity?
True or False? Work input is always greater than work output.
What is true?
This is the force that 'pushes' electrons to flow.
What is potential difference measured in Volts?
Elements that share electrons form this kind of bond.
What is covalent?
