What you receive
What you receive
- Angular momentum in kg m^2/s from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
The body rotates about a fixed principal axis and the stated moment of inertia applies.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
