# Free Fall Calculator

If you want to determine the velocity and distance covered by a falling object, then you can use our free fall calculator.

In physics, every **object's motion** in which only the **force of gravity is acting upon** it is known as **free fall**. There is one thing to note: in free fall, only the acceleration of gravity works, and no other external force can act on the object, including air resistance. The instant example of the above condition is the Moon's motion, where no force except the gravitational force is acting upon it. The value of gravitational force (g) is equivalent to 9.80665 m/s².

## Formula of Free Fall Calculator

To determine how to calculate the free-fall velocity of an object, you can use the formula listed below:

v = v₀ + gt

**Where,**

v₀ = Initial velocity (expressed in m/s or ft/s)

t = Time taken by an object to fall down (expressed in seconds)

g = free fall acceleration (expressed in m/s² or ft/s²)

**Note:**

To calculate the circumference, you can use our Circumference Definition.

### Example

For a more precise understanding of the free-fall concept, let us have an example below:

Suppose an object is felt towards the ground in 8s, whereas the initial velocity is 0 m/s. Find out the total velocity of an object in which it reaches the surface.

**Given data**

Inital velocity = v₀ = 0 m/s

Time = t = 8s

**To Find**

Free fall velocity = ?

**Solution**

To find out the free fall velocity of an object, we will use the formula listed below:

v = v₀ + gt

Putting values in the formula:

v = (0) + (9.80665)*(8) = 78.45 m/s

### How to use the Free Fall Calculator?

The steps to use the free fall calculator are as follows:

**Step 1: **Enter the value of the initial velocity of an object in the first required input.

**Step 2: **Enter the value of the time an object takes in the second required input.

**Step 3: **The calculator will automatically display an answer on the screen.
