Formula
L = Iฯ or L = mvr
Rotational analog of linear momentum. Conserved in the absence of external torques.
Worked Examples
Example 1: Spinning wheel
Problem:I=2 kgยทmยฒ, ฯ=5 rad/s
Solution:L=2ร5=10 kgยทmยฒ/s
Result:10 kgยทmยฒ/s
Frequently Asked Questions
What is momentum and how is it conserved?
Momentum is p = mv (mass times velocity). In a closed system with no external forces, total momentum is conserved. In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved but kinetic energy is not. Impulse (F*t) equals the change in momentum.
