Enter the initial velocity, final velocity, and total time passed into the calculator to determine the total deceleration.

## Declaration Formula

The following equation can be used to calculate the deceleration of an object.

D = vf – vi / t

- D is the deceleration (m/s^2)
- vf is the final velocity (m/s)
- vi is the initial velocity (m/s)
- t is the total time

## Deceleration Definition

Deceleration is defined as the rate of change of the reduction of speed of a moving object.

## Deceleration Example

How to calculate deceleration?

**First, determine the final velocity.**Measure the final velocity of the slowing object.

**Next, determine the initial velocity.**Measure the initial velocity.

**Next, determine the total time.**Measure the total time the object is slowing.

**Finally, calculate the deceleration.**Calculate the deceleration using the equation above.

## FAQ

**What is deceleration?**

Deceleration is the rate at which an object is losing speed. In other words, its the same as acceleration but it involves objects slowing down and not speeding up.

**How is deceleration calculator?**

Deceleration is calculate by the formula above using the inital and final velocities along with the time.
