explain linear momentum & angular momentum

Asked by varonika | 27th Jul, 2010, 12:00: AM

Expert Answer:

Linear momentum (SI unit kg·m/s, or, equivalently, N·s) is the product of the mass and velocity of an object (p = mv).

Angular momentum, moment of momentum, or rotational momentum is a conserved vector quantity that can be used to describe the overall state of a physical system. The angular momentum L of a particle with respect to some point of origin is

where r is the particle's position from the origin, p = mv is its linear momentum, and × denotes the cross product.
