The amount of matter contained in a space

The amount of 3D space a solid, gas, or liquid occupies

Relationship between mass and unit of volume

A material’s ability to conduct or resist electricity

Measures how fast heat moves through a material

The degree to which a material increases its dimensions when its heated

The resistance of a material to scratching or penetration

Properties of materials that are usually measured through some form of destructive testing

Properties of materials that can be measured through non-destructive testing

The ability of a material to resist pulling forces

The ability of a material to resist pushing forces

The ability to resist bending by a force so that an object maintains its shape when a force is applied to it

The ability to deform, but resist cracking/fracturing under impact.

The ability to be drawn or extruded into a wire-like form

The ability of a material to bend and then return to its original shape

The ability of a material to be formed into a new shape

Measure of the stiffness of an elastic material using the ratio of stress to strain of a material as force is applied along its length.

The tensile force applied to a given area

The percentage of change in length when a force is applied to the initial length

Space on a stress-strain graph where the material would return to its original shape if the material was stretched and then released.

The point on a stress-strain graph where the material will no longer return to its original shape

The point at which the material can maintain a maximum load.

A mode of tensile deformation where large amounts of strain localize disproportionately in a small region of the material

The point on a stress-strain graph at which the material actually breaks

Properties that are related to beauty and pleasure derived from a material

How a material feels or looks

The color or pattern of a material

Reactive materials that change their properties when exposed to stimuli such as electrical charges, moisture, or temperature

The ability to release an electric charge when deformed

Materials that allow their bodies to return to their original shape after deforming

The ability to change color when exposed to light

Fluids that undergo a change in their viscosity when a magnetic force is applied

Fluids that undergo a change in their viscosity when an electrical force is applied

Two different conductors that, when joined together, generate electricity when heat is applied.
