An object in water ... whether floating or completely submerged ... is acted upon by two forces in the vertical direction: 1). its weight, directed downward, equal to its (mass) times (acceleration of gravity) 2). its buoyancy, directed upward, equal to the weight of the water that it displaces
The greater the pressure against the bottom of a submerged object produces an upward buoyant force
Net force is the sum of all forces that act on an object. An unbalanced force means that net force is not equal to zero. If that is the case, the object will accelerate.Net force is the sum of all forces that act on an object. An unbalanced force means that net force is not equal to zero.

Upthrust which is equal to weight of fluid displaced

In the act of "throwing", the thrower imparts an upward velocity to the object, by temporarily applying an upward force to it that's greater than the downward force of gravity. During that brief period, the sum of the forces on the object is directed upward, so it accelerates in that direction. After the throwing ends, however, the only force on the object is the force of gravity, directed downward, so its acceleration is downward. That means that the upward velocity becomes smaller and smaller, until it's zero at the peak of the arc, and the velocity then becomes downward as the object begins to fall from its peak..
Normal force can act on an object

The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.

That's it. A force is a push or pull on an object.
when you act a force on it or on the object
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
the object will move
