This diagram describes the relationship between force (F), torque (τ), momentum (p), and angular momentum (L) vectors in a rotating system. 'r' is the radius. Credit: Yawe.
Angular momentum and energy are concepts developed to try to understand everyday reality.
An angular momentum L of a particle about an origin is given by
where r is the radius vector of the particle relative to the origin, p is the linear momentum of the particle, and × denotes the cross product (r · p sin θ). Theta is the angle between r and p.
Please put any questions you may have, and your results, you'd like evaluated, on the problem set's discussion page.
