The normal force of a table is the force that the table exerts on any object placed on its surface, perpendicular to the surface. It is also known as the support force.
The normal force of a table can be calculated by using the equation FN = mg, where m is the mass of the object and g is the acceleration due to gravity. This is based on Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.
The normal force of a table is affected by the mass of the object placed on it and the acceleration due to gravity. Other factors that can affect it include the angle of the surface, the material and shape of the table, and any additional forces acting on the object.
The normal force of a table is important to consider because it helps to determine the stability and support of an object placed on it. It also affects the amount of friction between the object and the table, which can impact its movement and motion.
Yes, the normal force of a table can be greater than the weight of an object. This occurs when the table is on an incline or has additional forces acting on it, such as an external force pushing down on the object. In this case, the normal force will be equal to the weight of the object plus any additional force acting on it.
