Enter the distance and velocity into the calculator to determine the seconds to impact. This calculator can also evaluate any of the variables given the others are known.

## Seconds To Impact Formula

The following formula is used to calculate the seconds to impact.

STI = d / v

Variables:

- STI is the seconds to impact (s)
- d is the distance to the object or ground (m)
- v is the velocity of the object or vehicle (m/s)

To calculate the seconds to impact, divide the distance to the object or ground by the velocity of the object or vehicle. This will give the estimated time remaining before the object or vehicle will collide with another object or the ground.

## What is Seconds To Impact?

Seconds to Impact is a term often used in aviation, space exploration, and military contexts to refer to the estimated time remaining before an object or vehicle will collide with another object or the ground. This measurement is crucial in emergency situations, allowing for quick decision-making and execution of necessary procedures to mitigate damage or avoid the collision. It can also be used in simulations or theoretical calculations.

## How to Calculate Seconds To Impact?

The following steps outline how to calculate the Seconds To Impact (STI).

- First, determine the distance to the object or ground (d) in meters.
- Next, determine the velocity of the object or vehicle (v) in meters per second.
- Next, gather the formula from above = STI = d / v.
- Finally, calculate the Seconds To Impact (STI) in seconds.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

distance to the object or ground (d) = 500

velocity of the object or vehicle (v) = 50
