100

The three primary states of matter on Earth; they are determined by the arrangement and motion of the matter's atoms or molecules.

What are solid, liquid, and gas?

100

The ability to cause motion or change.

What is energy?

100

A push or a pull on an object.

What is force?

100

Disturbances that carry energy from place to place, but the matter stays close to its original position.

What are waves?

100

Thermal energy transferred from one region or substance to another.

What is heat?

200

An element is a unique particle of matter.  An individual particle of an element is ________.

What is an atom?

200

The energy an object has because of its motion.

What is kinetic energy?

200

The rate of change of an object's velocity; it can be speeding up, slowing down, or changing direction.

What is accelerartion?

200

Waves that move in a motion perpendicular to the direction of the wave; these waves are S-shaped.

What are transverse waves?

200

The three methods for heat transfer.

What are conduction (through direct contact), convection (through gas or liquid), and radiation (via light waves)?

300

The connection between atoms in more complex particles.

What are chemical bonds?

300

A force that opposes motion between two surfaces that are in contact with one another, resulting in kinetic energy being transferred to thermal or sound energy.

What is friction?

300

Newton's 2nd law of motion acknowledges the relationship between acceleration (a), force (F), and mass (m).  The equation is written as ________.

What is a = F/m?

300

The distance between two successive crests in a wave.

What is wavelength?

300

The condition in which objects that are touching have the same temperature; objects and substances are always trying to reach this.

What is thermal equilibrium?

400

This organizes the known elements by both increasing order of their atomic mass and into columns of shared properties.

What is the Periodic Table of Elements?

400

The scientific law that states the total energy in a system always stays the same; energy can not be created or destroyed, just transferred or converted.

What is the law of conservation of energy?

400

These are the three types of non-contact forces.

What are magnetic, gravitational, and electrostatic?

400

The two properties of waves that have an impact on how much energy is transferred.

What are amplitude and frequency?

400

A material that has a low thermal conductivity, keeping heat from flowing through it easily.

What is a thermal insulator?

500

A chemical reaction is a process in which one or more substances form one or more other substances.  This type of chemical reaction releases more energy to the surroundings than it absorbs.

What is an exothermic reaction?

500

Potential energy is stored energy.  Name the five types of potential energy.

What is gravitational, electrical, magnetic, elastic, and chemical?

500

This states that an object at rest stays at rest, and an object in motion stays in motion with a constant velocity unless acted on by unbalanced forces.

What is Newton's first law of motion?

500

The units of measurement used to describe the amount of energy a wave has.

What are joules?

500

The property of a substance that describes the amount of thermal energy that is needed to raise the temperature of the substance.  For example, water has a much higher ________ than sand.

What is heat capacity?
