if you are asking in which direction does a liquid exert pressure on the object? then, liquid exert force in the upward direction which is called buoyancy. Brief description: when a body is partially or wholly immersed, it displaces the fluid. the displaced fluid had tendency to regain it's original position position. due to this, an upward force is exerted on the body by the displaced fluid. this upward force actiong on the the body immersed in a fluid is called upward thrust or buoyancy force or simply buoyancy.
The greater the pressure against the bottom of a submerged object produces an upward buoyant force
A buoyant force is produced when an object is completely or partially submerged in a fluid at rest .
Upthrust which is equal to weight of fluid displaced
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 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.

Buoyancy is the power to float or rise in a liquid and it acts against the force of gravity.
Friction always acts in a direction opposing the motion of an object.
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..
Buoyant force is defined as the upward force exerted by a liquid, gas or other fluid, that opposes the weight of an immersed object. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the objects. Because all of the objects displace the fluid, buoyant force acts on all of them.
Archimedes' principle refers to an object floating in a liquid. In this case, there is the downward force of gravity on the object, and the "buoyant force" as upward force. This is quite unrelated to "free fall", which means that no other forces than gravity act on an object.
Lifting force acting upward Weight of the object acting downward Both are equal and opposite to each other
