QUANTITY
vector quantities are in bold type
VARIABLE
(“the thing being measured”)
(” represented in
equations as:”)
UNIT
(“The international scientific community has
agreed to measure this quantity in a specific
amount known as a…”)
BASE QUANTITIES:
displacement
mass
time
* electric current
* electric charge
meter (m)
kilogram (kg)
second (s)
ampere (A) = (C/s)
coulomb (C) = amp-sec (A s)
d,x,y,s
m
t
I
q
(*although “charge” is a fundamental quantity, “current” is the base quantity, since it is much more simple for a
laboratory to measure electric current than to measure a static charge)
DERIVED QUANTITIES:
velocity
acceleration
force
momentum
gravitational field strength
(“acceleration due to gravity”)
pressure
P
energy (in general)
kinetic energy
potential energy
heat
work
power
E
K or KE
U or PE
Q
W
P
angle
angular velocity
angular acceleration
