## momentum

[mo-men´tum]
the quantity of motion; the product of mass by velocity.

## mo·men·tum

(mō-men'tŭm)
The tendency of an object in motion to continue in motion.
[L., abridgment of movimentum, movement]

## momentum

the 'quantity of motion' of a body or object. A vector quantity. linear momentum the product of mass and velocity. The change in linear momentum is equal to the linear impulse. conservation of linear momentum in the absence of external unbalanced forces, the total linear momentum of colliding bodies or objects will remain constant. Commonly applied to racquet/ball impacts. angular momentum the product of moment of inertia and angular velocity. conservation of angular momentum in the absence of an external moment (torque), the angular momentum of a rotating body will remain constant. Often applied to low-velocity flight (e.g. gymnastics) to explain how a body can increase or decrease angular velocity by manipulating moment of inertia (e.g. by 'tucking'). trading of angular momentum if, in the absence of an external moment (torque), an object or body is rotating about one axis (e.g. somersaulting) and rotation about another axis is introduced (e.g. tilt), the result will be a rotation about a third axis (e.g. twist) due to the vector nature of angular momentum. transfer of angular momentum can occur from one part of a body to another in the absence of an external moment (torque) (e.g. if one part of a body increases angular velocity, another part must decrease to conserve angular momentum).
