Speed is the rate of motion of an object.
describes an object's speed and
direction. The velocity of an object can
even if the speed of the object
remains constant. This would occur if the
of the object's motion changes.
The rate of change of velocity is called _
The size of an acceleration
depends on both the change in velocity and the
of the change.
To calculate acceleration,
the change in velocity by the time interval. To
find the change in velocity,
the initial velocity (v:) from the final velocity
(V.). The equation for average acceleration is
_. Final velocity will be less
than initial velocity if an object is
, and acceleration will have a
value. Final velocity will be greater than initial velocity if an object is
and acceleration will have a
value.
The units for velocity are
. The unit for time
Therefore, the units for acceleration are
