The normal force if the force of one object holding up anothe. Ex. a block of wood on the ground. The normal force is the force applied to the wood to prevent it from sinking.
In other words, it is the objects weight. W=mg, where W=weight, m=mass, g=force of gravity.

∙ 12y agoWhen two surfaces are in contact the "Normal" force is the perpendicular (to the surfaces) force that one surface exerts on the other. It is due to the molecular strength of the surface material. For example, if you're standing on the floor gravity (your weight) is pulling you down. If the floor would break you would drop down. If the floor does not break and you do not drop down then the floor must be pushing up on your feet to cancel the downward force of gravity. This is the Normal force exerted by the floor. The Normal force will be larger if you are heavier and it will be whatever it has to be to cancel the weight, until there is so much weight that the floor finally breakes. Another example; if you are pushed against the car door when going around a curve the car door exerts a normal force on you that keeps you from flying out. Another example; if two blocks are side by side. You push horizontally on the back block and both blocks move. The front block moves because the back block exerts a "Normal" force on it where their surfaces are in contact.

∙ 13y agoWhen a body is contact with a surface, a force is exerted by the body upon that surface. The surface is said to exert an equal and opposite force against the body known as the normal force, which is based on Newton's third law.
An example would be if a Person of 70kg was stood on the ground. Assuming that acceleration due to gravity is 10ms-2 then the person exerts a force of 700N on the ground. In opposition, the ground exerts a normal force of -700N on the person.

What determines the size of a frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
How do you find the magnitude in force?
Actually you answer itself is wrong. You can only find the magnitude of force, not the magnitude in force. You can find the magnitude of force by s = (1/2)*a*t^2
What force acts against the gravitational force that is in the upward direction?
In physics, there is a force that is called the normal force. This is the force that comes from a surface pushing up on an object. If the surface is level, the normal force is the exact same magnitude as the gravitational force, but straight up. The normal force is always perpendicular to a surface. Hope this helps!
Can force change the magnitude of a body?
Yes, force can change the magnitude of a body.
What is the size of a force called?
It is the magnitude of the force applied in Newtons or pounds
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
What determines the size of a frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
What information do you need to know in order for the magnitude of the normal force be equal to the magnitude of the gravitational force?
THE BODY IS AT REST IN THE VERTICAL DIMENSION.
How do friction and gravity relate?
The magnitude of friction is proportional to the magnitude of the normal force which is proportional to the magnitude of gravity(The magnitude of the normal force is indirectly proportional to the magnitude of gravity.). The magnitude of the normal force, N, compared to gravity, G, on angle z, is: N=cos(z)*G On a flat surface. N=G The coefficient of friction, whether static or kinetic, f is therefore: N=cos(z)*G*f
What would happen to an object when normal force and force of gravity is applied?
It depends on the magnitude of the forces.
What is the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
How do you find the magnitude in force?
Actually you answer itself is wrong. You can only find the magnitude of force, not the magnitude in force. You can find the magnitude of force by s = (1/2)*a*t^2

If Refers To The Size Or Strength Of The Force?
The "size" of a vector quantity - such as a force - is often called a MAGNITUDE.
What is a magnitude of force?
The magnitude of a force is its 'size' or 'strength', regardless of its direction.
What are some characteristics of net force?
1- It has direction. 2- It has magnitude. 3- It is the sum of all forces( normal + tangential). net force = square root( normal force2 + tangential force2).
What two factors that affect the amount of friction between two surfaces?
The magnitude of the frictional force is directly proprotional to the normal reaction between the two surfaces.(2)Magnitude of the frictional force is independent of shape and area of the surfaces
