When a mass is on a surface,It applies a force to it because of its weight.According Newton's 3rd law,the surface applies a force to the mass.Can we call this force,Normal force?
The normal force is the force exerted by a surface on an object in contact with it, perpendicular to the surface. It is called the "normal" force because it is always perpendicular to the surface, or "normal" to it.
The normal force is caused by the repulsive forces between the atoms or molecules of the surface and the object in contact with it. These forces are known as the electrostatic forces.
The normal force is not directly related to the mass of the object. It is dependent on the weight of the object, which is equal to its mass multiplied by the acceleration due to gravity. Therefore, the normal force increases as the weight of the object increases.
No, the magnitude of the normal force can vary depending on the weight of the object and the angle at which it is placed on the surface. For example, if the object is on an inclined plane, the normal force will be less than the weight of the object.
The normal force is a reactionary force that helps to balance out other forces acting on an object. It is essential in keeping objects stable and preventing them from sinking into a surface. In terms of motion, the normal force does not directly influence the acceleration of an object, but it plays a crucial role in maintaining equilibrium and preventing the object from falling through the surface.
