It depends on the magnitude of the force and the mass of the object
The force of friction acts against an object traveling horizontally, opposing its motion and causing it to slow down.
If the force is aligned with the horizontal, then its vertical component is zero.
A couple of perfect examples are: -- the driver sitting in a car cruising along a level highway -- the dog sitting in a little red wagon being pulled on level ground by a little girl. In each case, the passenger's weight is the gravitational force, acting vertically, while the vehicle is constrained to move horizontally. The gravitational force does no work in either situation, because the (vertical) distance through which it acts is zero.
Weight acts in the vertical direction, pulling an object towards the center of the Earth. It is a force due to gravity and is proportional to the mass of the object.
A bullet shot horizontally will experience a vertical acceleration due to gravity of 9.8 m/s^2, which acts downward. However, since there is no vertical propulsion force acting on the bullet, the vertical motion is purely due to gravity.

as work done is dot product of force and displacement so cos(90)=0;therfore work done is zero

A push or pull that acts on an object is a force.
When an unbalanced force acts on an object, it will cause the object to accelerate in the direction of the force. The greater the force applied, the greater the acceleration of the object. The direction of the force will determine the direction of the object's motion.
The quantity that combines the strength of a force with how long it acts on an object is called impulse. Impulse is calculated by multiplying the force by the time over which it acts on an object. It represents the change in momentum of the object.
If gravity did not affect a horizontally thrown ball, it would travel in a straight line horizontally at a constant velocity. Gravity only acts vertically, causing the ball to fall towards the ground, so without this vertical force, the horizontal motion would remain unaffected.
