No, not necessarily.

If only one force is acting and it is perpendicular to the velocity of body, it will not change the velocity and thus, no effect on momentum or K.E.

Approve if i helped :)

Yes as force = change in momentum per unit time therefore force must change a body''s momentum and hennce kinetic energy.
