Normal Force Calculator will determine the force exerted by a surface to prevent the object from falling. All you need to do is provide the inputs mass, degree of inclination and click on the calculate button to get the output.

**Normal Force Calculator: **Trying to figure out what is meant by Normal Force? If so, you
have landed on the right page and we will explain all about Normal Force Formulas, Steps on How to
Calculate Normal Force. You can find out normal force both in case of horizontal, inclined surfaces or
when an external force is applied using our handy tool.

Normal Force is a perpendicular force that a surface exterts on an object. For Example if we place an
object on a table the gravitational force will pull the object donwards. In order to prevent the object
from falling the table will exert certain force to prevent it from falling. This force is known as
Normal Force and is denoted by F_{N} or N. Normal Force units are Newton.

Normal Force typically follows the Prinicple of Newton's Third Law of Motion. Normal Force is a force of contact. It is a Force exerted only if two objects are in contact with each other. When two objects are touching one another then they exert a normal force on one another vertical to contracting surface.

If an object lies on a flat surface then the Normal Force is given by F_{N} = m*g

Where m is the mass of an object

g is the gravitational force

If an object is held on an inclined surface then the Normal Force Equation is given by F_{N} =
m*g *cos(α)

Where α is the surface inclination angle

**Normal Force Questions**

Example: A Body is placed on a table if the mass of an object is 2 kg. The Angle of inclination is 45°. Compute the normal force applied on the body?

**Solution:**

Given that

Mass m = 2 Kg

Angle θ = 45°

F_{N} = m * g * cos(α)

Substituting the inputs in the formula to calculate the normal force we get the equation as follows

F_{N}= 2*9.8*45°

F_{N} =13.87 N

**1. What is meant by Normal Force?**

Normal Force is a force exerted by a surface to prevent the object placed on it from falling.

**2. What is the formula for Normal Force if the object is placed on a flat
surface?**

The Formula to calculate normal force on a flat surface is given by F_{N} = m*g

**3. If the Object is at rest what is the net force acting on it?**

If the Object is at rest the net force acting on it is zero.

**4. Is Normal Force always equal to weight?**

In majority of the cases norma force is always equal to the weight if it is the only force counteracting. If there are any external forces you need to consider them too by applying Newton's Second Law.

**5. How to find Normal Force on an Incline?**

Normal Force can be found on an Incline using the formula F_{N} = m * g * cos(α)
