quantity comparison table

Subject has base unit has unit is a kind of has symbol is a component of is defined us has definition

angle angle unit quantity

angular momentum quantity L The product of mass and angular velocity for an object in rotation; similar to linear momentum. In quantum mechanics, angular momentum is quantized, i.e., is measured in indivisible units equivalent to Planck's constant divided by 2 pi. This corresponds classically to only certain frequencies of rotation being allowed.

area quantity

coordinate component quantity coordinate A component of a coordinate system, components are usually an angle or a length

density quantity An object's mass divided by its volume. Cotton has a low density; lead has a high density. Red giants have a low density; white dwarfs have a high density.

electromagnetic quantity quantity

energy energy unit quantity

equatorial sky area quantity equatorial coordinates A fixed region on the sky defined using equatorial coordinates

force quantity force unit quantity Agency responsible for a change in a system. In Newtonian mechanics, gravitational force bends the moon away from the straight trajectory it would otherwise pursue.

frequency frequency unit quantity ν Number of oscillations per second of an electromagnetic wave. The amplitude of a wave depends on the intensity; the wavelength, on the frequency.

length length unit quantity

mass mass unit quantity The measure of the inertia of an object, determined by observing the acceleration when a known force is applied. The gravitational force acting on an object is found to be proportional to its mass, as is the gravitational force that it exerts on other objects.

orbital quantity quantity A quantity used for calculating orbits

power quantity

pressure pressure unit quantity The force exerted over a surface divided by its area.

quantum quantity quantity

radiation measurement radiation unit quantity

solid angle quantity A measure of the angular size of an extended object, equal to the area it subtends on the surface of a sphere of unit radius.

statistical quantity statistical concept

temperature temperature unit quantity A measure of the average kinetic energy of the particles of a system.

time time unit quantity A dimension distinguishing past, present, and future. In relativity, time is portrayed as a geometrical dimension, analogous to the dimensions of space.

velocity length per unit time quantity The speed and the direction of an object's motion.
