Acceleration.
A balanced force has no effect on any object.
A state of rest or balance is when an object is not in motion or actively experiencing change. It is a state of stability where all forces acting on the object are in equilibrium, resulting in no acceleration or movement. In this state, the object remains stationary or maintains a constant velocity.
The book is experiencing a gravitational force pulling it downward towards the Earth, and a normal force exerted by the table pushing upward to support the weight of the book. These two forces are balanced, resulting in the book being at rest on the table.
When an object is at rest on a table top, the downward force of gravity is balanced by the upward normal force exerted by the table surface on the object. This balance of forces prevents the object from moving or accelerating in any direction.
An object can be at rest relative to a second object whilst in motion relative to a third object.For example, if you sit still then relative to the Earth you are at rest. However the Earth is both spinning on its axis and travelling around the Sun, so relative to an observer in space you are in motion. Einstein showed us that all such concepts are relative.
An object at rest on the surface of the Earth is experiencing the force of gravity pulling it downward, as well as the normal force acting upward from the surface to support its weight. These two forces are balanced in a state of equilibrium, resulting in the object staying still.

The velocity parallel to Earth's surface depends on the frame of reference. Relative to Earth's surface, the velocity is zero if an object is at rest, and it varies depending on the direction and speed of the object's movement. If we consider the rotation of the Earth, objects on the surface have an eastward velocity due to the planet's rotation.
The Earth's gravity stops the object from floating when at rest.
A balanced force has no effect on any object.
Friction.
There are lots of ifs in this question and answer. If the 100 pound Earth object could rest on the outer surface of Jupiter the answer would be 250 pounds. But, Jupiter is a gas planet. That is, Jupiter is primarily made of gas and liquid. So, the object could not rest on the outer surface. There may be a solid surface near it's center but no one knows. Jupiter is 318 times as heavy as Earth so if Jupiter were solid and the size of Earth the object would weigh 318 times a much or 31,800 pounds. But, it is much larger than Earth so the outer surface is much farther from the center. The farther away the object is from the center the less the object will weigh.
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
Approximately 29% of the Earth's surface is covered by land. The rest of the surface is covered by water bodies.
A state of rest or balance is when an object is not in motion or actively experiencing change. It is a state of stability where all forces acting on the object are in equilibrium, resulting in no acceleration or movement. In this state, the object remains stationary or maintains a constant velocity.
Continents cover about 29% of Earth's surface. The rest is mostly covered by oceans.
Will you accept heat? Or would you prefer the potential energy it has before falling down a well? It's all relative.
