Angular momentum calculator
Calculate angular momentum, moment of inertia, or angular velocity using L = I × ω. Supports SI units and step-by-step rotational motion solutions.
angular momentum calculator:
The Angular Momentum Calculator is used to compute L, I, or omega in rotating systems. The calculation is L = I × ω, and when the two known values are entered, the tool uses them to determine the unknown. The rotational motion solutions and unit conversions in steps calculate rotational motion easily for students, engineers, and laboratory operations.
angular momentum Converter Tool Formula:
Basic Angular Momentum: \( L = I \cdot \omega \)
Angular Momentum with Linear Momentum: \( L = r \cdot p \cdot \sin(\theta) \)
Angular Momentum with Mass and Velocity: \( L = m \cdot r \cdot v \cdot \sin(\theta) \)
Parameter Explanations:
- I: Moment of inertia (in kg·m²)
- \( \omega \): Angular velocity (in rad/s)
- r: Distance from the rotation axis (in meters, m)
- p: Linear momentum (in kg·m/s)
- \( \theta \): Angle between radius and momentum/velocity (in degrees)
- m: Mass of the object (in kg)
- v: Linear velocity (in m/s)
The Angular Momentum Calculator enables the user to calculate angular momentum (L), moment of inertia (I), or angular velocity (ω) of rotational systems. Angular momentum can be determined as L=I 0 w, with I being the moment of inertia of an object and 0 w being the angular velocity. We can also use the calculator to compute conservation of angular momentum in isolated systems, i.e., spinning discs, rotating planets, or mechanical flywheels.
The moment of inertia (kg·m²) and angular velocity (rad/s) may be entered by the user to compute L, or solve for an unknown I or 2 by giving an angular momentum. Solutions are presented step by step so that the formulas and calculations can be understood better. The tool accepts SI units: kg·m²/s for L, kg·m², and omega of rad/s. Additional options will be printable results and default settings of discs, spheres, and rods under rotational motion. This renders it the best choice among physics students, teachers, engineers, and mechanics who learn rotational dynamics.

Testing and Final Adjustments
Test common scenarios:
- I = 2 kg·m², ω = 3 rad/s → L = 6 kg·m²/s
- L = 10 kg·m²/s, ω = 5 rad/s → I = 2 kg·m²
- L = 15 kg·m²/s, I = 3 kg·m² → ω = 5 rad/s
Check unit conversions (kg·m²/s ↔ N·m·s), step-by-step clarity, and handling of edge cases (I or ω = 0). Validate UX: numeric keypad on mobile, field labels, error messages for missing inputs. Include presets for common objects like discs, rods, and spheres.
