What is Foot Per Second?
Foot Per Second Formula and Symbol
The formula to calculate speed in feet per second (ft/s) is:
Where:
- Speed is measured in feet per second (ft/s)
- Distance is measured in feet (ft)
- Time is measured in seconds (s)
How to measure the Foot Per Second
- Distance Measurement: First, determine the distance that you want to measure. This could be the length of a path, the distance between two points, or the length of time it takes for an object to move a certain distance. Use a measuring tape, ruler, or any other appropriate measuring tool to measure the distance in feet (ft).
- Time Measurement: Next, measure the time it takes for the object to travel that distance. You can use a stopwatch, a clock with a second hand, or any device that can accurately measure time in seconds (s). Start the timer when the object begins its motion and stop it when it reaches the end of the distance.
- Calculate Speed: Once you have both the distance and the time measurements, you can calculate the speed in feet per second (ft/s) using the formula: Speed = Distance/Time Simply divide the distance (in feet) by the time (in seconds) to obtain the speed in feet per second.
For example, if an object travels a distance of 50 feet in 5 seconds, the speed would be calculated as:
Speed = 50 feet/seconds = 10 ft/s

Examples of Foot Per Second
Automotive Speed
- Example: A car traveling at 30 feet per second is moving at about 20.45 miles per hour, a common speed in residential areas.
Athletic Tracking
- Example: In track and field, a sprinter’s speed is measured in feet per second during short distances to determine acceleration and performance.
Aeronautics
- Example: The takeoff speed of small aircraft might be measured in feet per second to ensure they achieve enough velocity for lift-off.
Ballistics
- Example: The initial velocity of a bullet fired from a gun can be expressed in feet per second to assess its potential impact and trajectory.
Industrial Machinery
- Example: Conveyor belts in a manufacturing plant are often rated by how many feet per second they can move products along the production line.
River Flow Rates
- Example: Hydrologists measure the speed of river currents in feet per second to help predict water behavior during different seasons.
Architectural Engineering
- Example: Elevators are sometimes designed with specifications on how many feet per second they can safely ascend or descend.
Robotics
- Example: Robots in assembly lines are programmed to move components at a precise rate, often measured in feet per second, to sync with other machinery.
Recreational Sports
- Example: In sports like soccer, the speed of a kicked ball can be measured in feet per second to analyze its potential to evade the goalkeeper.
Maritime Navigation
- Example: The speed of boats or small watercraft may be measured in feet per second, especially during docking procedures to ensure safe harbor entry.
Types of Foot Per Second
- Linear Speed: In physics and engineering, “foot per second” often refers to linear speed, which is the distance traveled per unit of time. For example, the speed of a moving vehicle, the velocity of an object in free fall, or the flow rate of fluids in pipes can all be expressed in feet per second.
- Wind Speed: Meteorologists commonly use “foot per second” to measure wind speed. Wind speed is the rate at which air moves horizontally past a fixed point and is typically measured in various units, including feet per second.
- Projectile Motion: In ballistics and sports, “foot per second” is used to describe the velocity of projectiles or objects. For instance, the muzzle velocity of a firearm or the speed of a pitched baseball might be expressed in feet per second.
- Fluid Mechanics: Engineers and scientists working with fluid dynamics may use “foot per second” to describe the velocity of fluids, such as water flow in rivers or channels, airflow in ventilation systems, or the speed of objects moving through a fluid medium.
