Acceleration
Acceleration
, in
physics
, is the
rate
of change of
velocity
of an object. An object's acceleration is the net result of any and all
forces
acting on the object, as described by
Newton's Second Law
. The
SI
unit for acceleration is
metre per second squared
(m s
-2
). Accelerations are
vector
quantities (they have
magnitude
and
direction
) and add according to the
parallelogram law
. As a
vector
, the calculated net
force
is equal to the product of the object's mass (a
scalar
quantity) and its acceleration.
