## Terminal Velocity Formula

The following equation is used to calculate the terminal velocity of an object.

- Where m is the mass of the object
- g is the acceleration due to gravity
- p is the density of the medium (air)
- A is the cross-sectional area
- Cd is the coefficient of drag

## Terminal Velocity Definition

A terminal velocity is defined as the maximum speed of a falling object where the force of gravity and force of air resistance is equal.

## Terminal Velocity Example

How to calculate terminal velocity

**First, measure the mass of the object**Measure the mass of the object in kilograms.

**Next, determine the acceleration due to gravity**On earth, this is approximately 9.8 m/s^2.

**Next, determine the density of air**Air has a density of 1.225 kg/m^3 at 1 atmosphere.

**Next, measure the cross sectional area**The cross-sectional area is the area that is exposed to the force of air resistance.

**Determine the coefficient of drag.**Using an experiment or theoretical data, determine an estimate for the coefficient of drag on the object.

## FAQ

**What is terminal velocity?**

Terminal velocity is the maximum speed an object achieves while under free fall. At a certain speed, the force of gravity and the force of drag are equal, so the object doesn’t accelerate any further.
