'Feet per second' (Or 'foot per second') is a
unit of both
speed (scalar) and
velocity (vector quantity, e.g. 3ft/s west). It expresses the
distance in
feet (''ft'') traveled or displaced, divided by the
time in
seconds (''s'', or ''sec'').The equivalent
SI unit is the '
Metre per second'.
Abbreviations include 'ft/s', 'ft/sec' and 'fps', although the representation 'ft s
-1' is not often used.
