Answer #1

definitely, net force acting on a moving object is in the direction of motion.On a physical body, if a large number of forces acting on it,then we obtain a net force.The direction of that force decides the direction of motion.Suppose a force acting on body in x-direction,then due to this force body starts changing its position along x-direction.change in position with time gives the velocity and change in velocity gives the acceleration.So from Newton's 2nd law

here F and a has the same direction.
