Mechanics
How compact something is, i.e., mass per unit volume.
What is density?
A thermometer with a narrow range and a constriction at the bottom.
What is a clinical thermometer?
A wave in which the motion of the particles is perpendicular to the direction of motion of the wave.
What is a transverse wave?
The region of space where an electric force can be experienced.

What is specific heat capacity?
The ratio of the sine of the incident angle to the sine of the refracted angle.
What is refractive index?
How easily a magnetic field can pass through an object or substance.
What is permeability?
When heavy elements are broken apart by bombarding them with neutrons.
What is fission?
The product of a force and the perpendicular distance from the line of action of the force to the pivot.
What is the moment of a force?
The transfer of heat energy by wholesale movement of particles brought about by density changes.
