Energy Formula:
| From: | To: |
The Ft Pound Energy Formula calculates kinetic energy in foot-pounds using mass in slugs, velocity in feet per second, and gravitational acceleration in feet per second squared. It provides a measure of the energy possessed by a moving object in the imperial system.
The calculator uses the energy formula:
Where:
Explanation: The formula calculates kinetic energy by taking half the product of mass and velocity squared, divided by gravitational acceleration.
Details: Accurate energy calculation is crucial for engineering applications, ballistics, mechanical systems design, and understanding the energy transfer in physical systems using imperial units.
Tips: Enter mass in slugs, velocity in ft/s, and gravitational acceleration in ft/s². All values must be valid positive numbers.
Q1: What is a slug as a unit of mass?
A: A slug is the imperial unit of mass equal to approximately 14.5939 kilograms. It's defined as the mass accelerated at 1 ft/s² by a force of 1 pound.
Q2: Why is gravitational acceleration included in the formula?
A: Gravitational acceleration is used to convert the result into foot-pounds, which is a unit of energy in the imperial system.
Q3: What are typical values for gravitational acceleration?
A: Standard gravitational acceleration is approximately 32.174 ft/s² at sea level on Earth.
Q4: Can this formula be used for any object?
A: This formula calculates kinetic energy for objects in linear motion. For rotational motion or other energy forms, different formulas apply.
Q5: How does this relate to the metric system energy calculation?
A: In metric system, kinetic energy is calculated as E = 0.5 × m × v², with mass in kilograms, velocity in m/s, resulting in joules.
