Answer:
Explanation:
Scalar quantity is described as such quantities measured which has only magnitude but not direction.
Force when applied on any object is always denoted and comes with direction. It is always necessary to represent force is acting on which direction.
Hence force is not a scalar quantity. It is a vector quantity as it has magnitude as well as direction.
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.
