The two forces are gravity and normal force.
Air pressure.
Lifting force acting upward Weight of the object acting downward Both are equal and opposite to each other
Two forces acting in the same direction add together. If those two forces are acting on an object, the object will accelerate faster than if there was only one force acting on the object.

The force of gravity, which pulls it down; and friction forces, which pull it up.
If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.
Net force is a combination of all the foces acting on an object.If two forces are acting in the same direction you add the forces to calculate the net force
Air pressure.
Tension forces are two forces acting on one object, moving in opposite directions (away from one another) to stretch the object. Compression forces are two forces acting on one object, moving in opposite directions (towards one another) to compress or deform the object.
Lifting force acting upward Weight of the object acting downward Both are equal and opposite to each other
Two forces acting in the same direction add together. If those two forces are acting on an object, the object will accelerate faster than if there was only one force acting on the object.
If the sum of all forces acting upon an object is not zero, then the object will accelerate. (Newton's first law)

An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
The equation is a+b=c. If two forces act on an object in the same direction (a and b) then the net force ( c ) is equal to sum of the two acting forces.
