What happens when an object is at rest on a table top?
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.
What does support force do in physics?
A support force in physics is a reaction force that acts to prevent an object from falling through a surface. It is typically exerted by a solid surface such as the ground or a table in response to the weight of an object resting on it. This force is equal in magnitude but opposite in direction to the force of gravity acting on the object.
How the reaction force will act on an object while pulling and pushing the object placed on a table?
When pulling an object on a table, the reaction force will be equal and opposite to the pulling force exerted on the object. When pushing an object on a table, the reaction force will be equal and opposite to the pushing force exerted on the object. In both cases, the table exerts a reaction force to prevent the object from moving.
If an object weighs 12N how much pressure is exerting on the table?
Pressure is calculated by dividing the force exerted (12N) by the area over which the force is distributed. If the object is resting evenly on a flat surface, the pressure would be 12N divided by the surface area of contact with the table.
What is the reaction to the partner of an object sitting on a table Is the reaction force the normal force of the table acting upward to hold the object up If not then what is the correct reaction?
Yes, the reaction force to the partner of an object sitting on a table is the normal force acting upward to hold the object up. It is a result of Newton's third law of motion, where the table exerts an equal and opposite force on the object to support it against gravity.

When studying the effect of an applied force on the motion of an object why do you place the object on a level table top?
Placing the object on a level table ensures that the force applied to the object is the main cause of its motion, not any other external factors like the incline of the surface. This helps isolate and accurately observe the effects of the applied force on the object's motion.
Is force always needed to slow down an object?
No, force is not always needed to slow down an object. In cases where there is friction or air resistance, these forces can naturally slow down an object without the need for external force. For example, a ball rolling on a table will slow down due to the friction between the ball and the table surface.
What is support force?
If you are holding a 10 N book, you are providing a 10 N force directed upwards to oppose the book's weight. Or if it's sitting on a table, the table is providing a 10 N force directed upwards. Some might call that force a support force.
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.
Are there forces acting on the book if yes draw the forces acting on the table?
Yes, there are gravitational and normal forces acting on the book. The gravitational force acts downwards towards the center of the Earth, while the normal force acts perpendicular to the surface of the table and supports the weight of the book.
Where does the energy goes as an object is pushed across a surface when work is done against the force of friction?
The missing energy goes to heat the surface areas of the table and the sliding objectthat rub together.
What are the examples of limiting friction?
If limiting friction is the same as static friction, then I have an answer, because static friction means that the objects in contact do not move. For example, if you place a box on the table, it does not move, as there is static friction between the box and the table.
