Is the resultant force same as the change in velocity??
No.
F = ma. You still have the mass of the object to consider.
I suppose POP was really asking:
Is the direction of the force same as the direction of the change in velocity?
Will the answer still be a 'No'?
The answer will be yes if POP was asking about the directions of force and "change in velocity". As acceleration is the rate of change in velocity (alternatively, you can say force is the rate of change of momentum), the vector direction of acceleration and resultant force is the same.

On the other hand, if we take POP222's question as it is, force and velocity are different physical quantities and ThunderFbolt will be right.
They do not even share the same units. This is a tell-tale sign that they are not the same.
