100
The two "signs" of electric charge.
What are positive and negative?
100
The two "poles" of every magnet.
What are north and south?
100
The energy of motion.
What is kinetic energy?
100
A weight hung from a fixed point so that it can swing freely backward and forward, often used to demonstrate the conversion between kinetic and potential energy.
What is a pendulum?

What are Tesla (T)?
200
The source of all positive charge.
What are protons?
200
The things that magnets can exert a magnetic force on.
What are metals and other magnets?
200
The energy an object has because of it's position or state.
What is potential energy?
200
A force that can push or pull an object without physically touching it (e.g., gravity or magnetism).
What is a non-contact force?
200
This unit of distance is equal to the distance that light travels in a single vacuum year (about 9.5 trillion km).
What is a light-year?
200
The units of electric charge.
What are Coulomb (c)?
300
The source of all negative charge.
What are electrons?
300
What is the rule for magnetic force regarding the poles of the magnet?
opposite poles attract, like poles repel
300
What principle says a pendulum can never swing higher than it's original position unless acted upon by an external force?
The Law of Conservation of Energy.
300
A subatomic particle with no electric charge, found in the nucleus of an atom.
What is a neutron?
300
In genetics, this term describes the physical appearance of a trait (like blue eyes), as opposed to the genetic code.
What is a phenotype?
300
The standard voltage of wall outlets in Thailand (like the ones on your table).
What is 220V?
400
What is the rule for electric force, regarding charges and their sign?
opposites attract, like charges repel
400
A device that uses the Earth's magnetic field to indicate the cardinal directions anywhere on Earth.
What is a compass?
400
An object gains kinetic energy when it falls. Where did it get this kinetic energy from?
From it's initial gravitational potential energy.
400
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
What is an electric field?
400
The mathematical representation of Newton's Second Law.
What is
F=m*a?
400
The common name for electric arcs caused by static electric buildup in clouds exceeding the dielectric breakdown point of air.
What is lightning?
500
A unit that measures the "strength" of electricity.
What are volts (V)?
500
The two things that affect the magnetic force exerted by a magnet (you must name both).
What are the strength of the magnet and the distance from the magnet?
500
When you lift an object above the floor (or any reference point) you give it gravitational potential energy that it didn't have before. Where did this energy come from (hint: it's not your kinetic energy, the object would still have gravitational potential energy after you've stopped moving it upwards).
From the chemical energy stored within your body (transferred through your muscles and such).
500
The energy stored in a charged object due to its position in an electric field.
What is electric potential energy?
500
The elements in the far right side of the periodic table of elements are known as this.
