A box is sitting on a table. The upward force exerted on the box that stops it from falling through the table is known as the force.?
A box is sitting on a table. The upward force exerted on the box that stops it from falling through the table is known as the force.
Why won't a book resting on a table fall to the ground?
Because the table is exerting an upward force on the book exactly equal and opposite to the force of gravity.
What kind of force will a stack of magazines exert on a table?
The kind of force that a stack of magazines exert on a table is known as gravitational force. This is considered to be a type of potential energy.
Why does an object on a table not crash to the ground?
The object has weight - that is, gravity is pulling it down.However, the table is in the way, and it gets "squashed" by the object's weight, so it exerts a "normal reaction force" upwards on the object.The downward weight and upward reaction force cancel out, so the book stays still on the table.
What is an example of a balanced force acting on an object?
Take the example of a book resting on a table. The downward force of the book's weight is matched exactly by the upward resistance of the table - hence the book remains where it is. (If the table was very flimsy, and unable to support the weight of the book, the book would accelerate towards the ground.)

Is a textbook on a table a balanced force or an unbalanced force?
A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.
What describes unequal forces acting on a object-results in a change in the objects motion in the direction of the larger force?
Picking up a glass of beer from the table. Force of gravity . . . down. Force of arm muscle . . . upward. Forces are unequal. Upward force is greater than downward force. Glass accelerates upward, toward mouth.
What is support force?
Support force refers to the upward force exerted by a surface to counteract the downward force of an object resting on it. It prevents the object from falling through the surface due to gravity. Support force can also be known as normal force.

Why is the upward force applied by a table on book kept on it called a self-adjusting force?
When the book is on the table the force of gravity tries to pull it down to the center of the earth. But according to Newton's third law of motion the every action has an equal and opposite reaction. Thus the table applies the same force on the book as well. This is called a self-adjusting force as the table tries to remain in its original state i.e. its lowest potential state.

Can the force by an electric field be greater than the force due to a gravitational field?
Of course. When you wave a charged comb over bits of tissue on the table, they jump up off the table and stick to the comb. The electrostatic field of the comb must be attracting them upward with greater force than the gravitational field pulling them down.
A coin placed 30 cm from center of a rotating table horizontal turn table slips when speed is 50cm.s what provides the central force when the coin is stationary?
gravity keeps the coin inthe middle when its stationary
