Solution
Dear Student,
We
know
velocity
has
magnitude
and
direction
.
When
object
moves
in
circular
motion
,
direction
of
the
motion
changes
continuously
.
As
direction
changes
,
velocity
also
changes
continuously
hence
it
is
said
to
be
accelerates
motion
.
Tangent
at
point
on
the
circle
,
gives
the
direction
of
the
motion
,
now
at
different
points
,
tangents
ahve
different
directions
so
direction
is
not
same
for
two
points
.
