Energy Formula:
From: | To: |
Energy in foot-pounds (ft-lb) is a unit of work or energy in the English system. It represents the energy transferred when a force of one pound acts through a distance of one foot in the direction of the force.
The calculator uses the energy formula:
Where:
Explanation: The equation calculates the mechanical work done or energy expended when a force moves an object over a distance.
Details: Calculating energy in foot-pounds is essential in mechanical engineering, physics, and various applications involving work, torque, and energy transfer measurements.
Tips: Enter force in pounds (lb) and distance in feet (ft). All values must be valid positive numbers (force > 0, distance > 0).
Q1: What is the difference between foot-pounds and Newton-meters?
A: Foot-pounds is the English unit of energy/work, while Newton-meters is the metric unit (SI). 1 ft-lb ≈ 1.3558 N·m.
Q2: Can this calculator be used for torque calculations?
A: While torque also uses ft-lb units, torque is a rotational force, not linear work. The concepts are related but applied differently.
Q3: What are typical applications of foot-pound energy calculations?
A: Used in mechanical systems, ballistics, engineering design, and anywhere work or energy needs to be measured in English units.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise for the given inputs. Accuracy depends on the precision of your force and distance measurements.
Q5: Can negative values be used?
A: No, the calculator only accepts positive values as physical force and distance cannot be negative in this context.
