# Free Fall Acceleration Calculator

### Introduction

A free fall acceleration calculator helps determine the acceleration of an object falling solely under the influence of gravity. This tool is essential in physics to understand the dynamics of free-falling objects without air resistance.

### How to Use

To use the free fall acceleration calculator, follow these simple steps:

- Input the height from which the object is falling.
- Press the "Calculate" button.
- The calculator will display the time taken for the object to fall and its final velocity.

### Formula

The most accurate and commonly used formula for free fall acceleration without air resistance is:

where:

- v is the final velocity,
- g is the acceleration due to gravity (approximately 9.8 m/s² on Earth),
- h is the height.

### Example Solve

Suppose an object is dropped from a height of 100 meters. Using the formulas:

Thus, the object will take approximately 4.52 seconds to reach the ground and will be traveling at a velocity of about 44.27 m/s upon impact.

### FAQs

**What is free fall?**

Free fall is the motion of an object where gravity is the only force acting upon it.

**Does air resistance affect free fall calculations?**

This calculator assumes no air resistance. In real-life scenarios, air resistance can affect the fall.

**What is the value of gravitational acceleration (g)?**

The standard value of gravitational acceleration on Earth is approximately 9.8 m/s².

**Can this calculator be used on other planets?**

Yes, but you need to use the specific gravitational acceleration value for the respective planet.

### Conclusion

A free fall acceleration calculator is a handy tool for quickly determining the dynamics of a free-falling object. By inputting the height, you can easily find out the time and velocity of the fall using the formulas provided.
