It's not. If the forces on an apple were unbalanced, then the apple would accelerate.
As long as the apple is on the tree, the downward force of gravity is balanced by the
upward tension in the stem. When the upward tension in the stem goes away, the forces
are no longer balanced, and the apple accelerates in the direction of the remaining
unbalanced net force. It continues accelerating in that direction until it hits the ground,
whereupon the ground begins to provide an upward normal constraint force, which
once again balances the force of gravity, and the acceleration ceases. All of this takes
place without the slightest awareness on the part of the apple.
The force that pulls the apple down is gravity. When the apple is at rest on the tree, the forces are balanced between gravity pulling the apple down and the tree branch pushing up on the apple. Once the apple falls, gravity becomes the unbalanced force causing it to accelerate towards the ground.
Newton reasoned that the force of gravity pulling the apple towards the ground was the unbalanced force causing the apple to fall.
No, an unbalanced desk is not an example of an unbalanced force. An unbalanced force refers to a force that causes motion or a change in motion, while an unbalanced desk is simply an object that is not level.
Newton knew that there was an unbalanced force acting on the moon and the falling apple through sheer logic. He realized that things only went down. The idea that what goes up must come down proved there was a scientific reason for this. He also realized there was a pressure or force in between objects that were standing still and whatever it was they were sitting on.The legend is that Newton made the connection between the two questions when he watched a falling apple. He knew that unbalanced forces are needed to change the motion of objects by changing the velocity of the objects. He concluded that an unbalanced force on the moon kept the moon moving circularly around Earth. Newton said that these two forces are actually the same force- a force that he called (gravity)
The force that governs the motion of an apple falling from a tree is gravity. Gravity is the force of attraction between two objects with mass, and it pulls the apple towards the center of the Earth, causing it to fall.

Universal gravitation.....
Universal gravitation.....
the branch holds up the apple. This is the force of the tree branch on the apple

When an object accelerates, the force is unbalanced.
what is an unbalanced force in a short story
Gravity
The force that governs the motion of an apple falling from a tree is gravity. Gravity is the force of attraction between two objects with mass, and it pulls the apple towards the center of the Earth, causing it to fall.
Unbalanced force means the Net Force. So if there was a force of 6N to the left and 4N to the right the unbalanced or net force would be 2N to the left.
