# Normal Force Calculator

# Introduction

Calculating normal force is crucial in physics to understand the force exerted by a surface to support an object against gravity. A normal force calculator simplifies this process, providing an easy way to determine the force acting perpendicular to the surface. In this article, we will guide you through creating a functional normal force calculator.

# How to Use

To use the normal force calculator, follow these simple steps:

- Input the mass of the object in kilograms.
- Enter the gravitational acceleration (typically 9.8 m/s² on Earth).
- Click the “Calculate” button to obtain the normal force.

# Formula

The formula to calculate normal force (N) is given by:

*N*=*m*⋅*g*

Where:

*N*is the normal force,*m*is the mass of the object,*g*is the gravitational acceleration.

# Example Solve

Let’s solve an example:

If the mass (*m*) is 5 kg and gravitational acceleration (*g*) is 9.8 m/s², the normal force (*N*) is calculated as follows:

# FAQs

**Q1: What is normal force in physics?**

**A1:** Normal force is the force exerted by a surface that supports an object resting on it, acting perpendicular to the surface.

**Q2: Can normal force be negative?**

**A2:** No, normal force is always positive or zero. It counteracts the force of gravity and prevents objects from falling through surfaces.

**Q3: Why is gravitational acceleration used in the formula?**

**A3:** Gravitational acceleration is used to account for the force of gravity acting on the object.

# Conclusion

Creating a normal force calculator is a straightforward way to understand the force supporting an object against gravity. This tool proves valuable in physics and engineering applications, providing quick and accurate results.
