Matter & Its Properties
This state of matter has a definite volume but no definite shape.
What is a liquid?
This is a push or a pull exerted on an object.
What is force?
This is the center of an atom, containing protons and neutrons.
What is the nucleus?
This type of energy is often called "energy of motion."
What is kinetic energy?
This type of material, like copper, allows electricity or heat to flow through it easily.
What is a conductor?
This term describes the amount of space an object takes up.
What is volume?
This force works against the motion of two surfaces sliding past each other.
What is friction?
This subatomic particle has a negative charge and moves around the nucleus.
What is an electron?
This term describes energy that is stored or "in waiting."
What is potential energy?
This is a material that does not allow heat or electricity to flow through it well.
What is an insulator?
This is the temperature at which a solid becomes a liquid.
What is the melting point?
This property of an object describes its tendency to resist any change in its motion.
What is inertia?
This number, found on the Periodic Table, represents the number of protons in an atom’s nucleus.
What is the atomic number?
This type of wave requires a medium (like air or water) to travel through.
What is a mechanical wave?
This is a complete, unbroken path through which electric charges can flow.
What is a circuit?
This physical property is calculated by dividing an object's mass by its volume.
What is density?
According to Newton's Second Law, force is equal to mass multiplied by this.
What is acceleration?
These are the substances found on the left-hand side of a chemical equation.
What are reactants?
This is the distance between two consecutive crests or troughs of a wave.
What is wavelength?
This device uses an electric current to create a temporary magnetic field.
What is an electromagnet?
Melting an ice cube or boiling water are examples of this kind of change, where no new substance is formed.
What is a physical change?
This law states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
This law states that matter is neither created nor destroyed during a chemical reaction.
What is the Law of Conservation of Mass (or Matter)?
This is the bending of light as it passes from one medium to another.
What is refraction?
This device converts mechanical energy into electrical energy using magnets and wire coils.
What is a generator?
