Because force always has a direction, it always works towards or against something.
you might know that force,
is rate of change of momentum i. e
force = m (v-u) / t
= (mv - mu) / t
as we know momentum is a vector quantity so, the rate of change of momentum i. e Force would also be a vector quantity.
momentum = mass * velocity
velocity has a direction so,
momentum has also got a direction.
so, momentum is also a vector quantity.
