Best Answer

Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.

Why is the support force on an object called the normal force?

The support force on an object is called the normal force because it is perpendicular (normal) to the surface on which the object rests. It acts in the opposite direction to the force of gravity to keep the object in equilibrium.


What force acts against the gravitational force that is in the upward direction?

The force that acts against the gravitational force in the upward direction is typically the normal force. The normal force is the force that a surface exerts on an object in contact with it, pushing against the force of gravity.


What kinds of forces can act on an object?

Normal force can act on an object


Can a frictionless surface exert normal force?

No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.


Other names for normal force that opposes gravity?

Other common names for the normal force that opposes gravity are support force, contact force, and reaction force.


What is normal reaction?

Normal reaction refers to the force exerted by a surface in response to an object pressing against it. It is always perpendicular to the surface and acts to support the weight of the object resting on it, preventing it from falling through the surface.


Is normal force supplied by the strength of the surface?

A normal force is a force perpendicular to something - for example, to a surface. This force can be supplied by just about anything; in many cases by gravity.A normal force is a force perpendicular to something - for example, to a surface.

What relationship exists between the static frictional force and the normal force on an object?

The static frictional force is directly proportional to the normal force acting on an object. As the normal force increases, so does the maximum static frictional force that can be applied before the object starts moving. This relationship is described by the equation (f_{\text{friction}} \leq \mu_s \times N), where (f_{\text{friction}}) is the static frictional force, (\mu_s) is the coefficient of static friction, and (N) is the normal force.
