Explain how the motion of an object is effected when the forces acts on it

Assume you are mentioning the net force acting on an object.

Then, according to Newton's Second Law: F = ma, the direction of net force will be the same as the acceleration.

In other words, the object will possess an acceleration immediately, the velocity of the object along this direction will increase with time going by, providing the force constantly applying
