How the Foot Pounds of Energy Calculator Works

Energy in physics can be calculated in multiple ways, depending on the type of energy involved:

1. Kinetic Energy (Energy of Motion)

Kinetic energy is the energy an object possesses due to motion. The formula in foot-pounds is:

KE (ft-lb) = (Mass (lb) × Velocity (ft/s)^2) ÷ (2 × g)

Where:

  • Mass is in pounds (lb)
  • Velocity is in feet per second (ft/s)
  • g = 32.174 ft/s² (gravitational constant for pound-mass conversion)

2. Potential Energy (Energy from Position or Force)

When a force is applied over a distance, energy is calculated as:

PE (ft-lb) = Force (lb) × Distance (ft)

3. Energy Unit Conversion

  • Foot-Pounds to Joules:
1 ft-lb ≈ 1.35582 J
  • Joules to Foot-Pounds:
1 J ≈ 0.73756 ft-lb

Step 1: Enter Required Values

Input mass and velocity for kinetic energy or force and distance for potential energy calculations.

Step 2: Click Calculate

The calculator instantly computes energy in foot-pounds.

Step 3: Optional Conversion

Convert results to joules or other energy units if necessary.

Plain Text Formulas

  1. Kinetic Energy in Foot-Pounds:
KE (ft-lb) = (Mass (lb) × Velocity (ft/s)^2) ÷ (2 × g)
  1. Potential Energy in Foot-Pounds:
PE (ft-lb) = Force (lb) × Distance (ft)
  1. Convert Foot-Pounds to Joules:
Energy (J) = Energy (ft-lb) × 1.35582
  1. Convert Joules to Foot-Pounds:
Energy (ft-lb) = Energy (J) × 0.73756

Example Calculations

Example 1: Kinetic Energy of a Moving Object

  • Mass: 15 lb
  • Velocity: 25 ft/s

Calculation:

KE = (15 × 25^2) ÷ (2 × 32.174)  KE = (15 × 625) ÷ 64.348  KE ≈ 9375 ÷ 64.348 ≈ 145.7 ft-lb

Result:
The object’s kinetic energy is 145.7 ft-lb.

Example 2: Potential Energy from Force and Distance

  • Force: 40 lb
  • Distance: 6 ft

Calculation:

PE = 40 × 6 = 240 ft-lb

Result:
The energy is 240 ft-lb.

Example 3: Converting Foot-Pounds to Joules

  • Energy: 240 ft-lb

Conversion:

Energy (J) = 240 × 1.35582 ≈ 325.4 J

Result:
240 ft-lb is approximately 325.4 Joules.
