Enter a value for all fields

The **Distance Traveled at Constant Acceleration** calculator computes the distance traveled (**dx**) by an object after a period of time (**t**), based on its initial distance from the origin (x), the object's initial velocity (V) and a constant acceleration (**a**).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**x**) Initial Displacement_{0} - (
**V**) Initial Velocity_{0} - (
**a**) Constant acceleration - (
**t**) Duration of Travel

**Distance(dx):** The calculator returns the distance traveled in meters. However, this can be automatically converted into other length or distance units via the pull-down menu.

*distance traveled a.k.a. displacement*

The formula for the distance traveled with constant acceleration is:

dx = x+v⋅t+½⋅a·t²

where:

- dx is the distance traveled under constant acceleration
- x is the initial distance
- v is the initial velocity
- a is the constant acceleration
- t is the time of travel.

A common application for this equation is the travel associated with the free fall of an object under the force of gravity. In the case of Earth's gravity, the constant acceleration is approximately 9.80665 m/s^{2}. Note that this formula does not include other forces such as drag.

Note, the first derivative of this equation with respect to time is:

`dx/dt = a*t + v`

Since dx/dt represents change in distance over time, which is the definition of velocity, the formula could read:

`v_f = a*t + v_i`

where:

- v
_{f }= final velocity - a = constant acceleration
- t = time duration of constant acceleration
- v
_{i }= initial velocity

This would give you the velocity of the object after the same amount of time.
