Principle of vis viva
(Mech.)
the
principle
that
the
difference
between
the
aggregate
work
of
the
accelerating
forces
of
a
system
and
that
of
the
retarding
forces
is
equal
to
one
half
the
vis viva
accumulated
or
lost
in
the
system
while
the
work
is
being
done
.
Vis impressa
(Mech.)
force
exerted
,
as
in
moving
a
body
,
or
changing
the
direction
of
its
motion
;
impressed
force
.
Vis inertiæ
a
-
The
resistance
of
matter
,
as
when
a
body
at
rest
is
set
in
motion
,
or
a
body
in
motion
is
brought
to
rest
,
or
has
its
motion
changed
,
either
in
direction
or
in
velocity
.
b
-
Inertness
;

Vis mortua
(Mech.)
dead
force
;
force
doing
no
active
work
,
but
only
producing
pressure
.
Vis vitæ
(Physiol.)
vital
force
.
Vis viva
(Mech.)
living
force
;
the
force
of
a
body
moving
against
resistance
,
or
doing
work
,
in
distinction
from
vis mortua
,
or
dead
force
;
the
kinetic
energy
of
a
moving
body
;
the
capacity
of
a
moving
body
to
do
work
by
reason
of
its
being
in
motion

vis viva
is
not
usually
understood
to
