Momentum

Meanings

Of a body in motion: the tendency of a body to maintain its inertial motion; the product of its mass and velocity.

Momentum: In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and
Angular momentum: Angular momentum (sometimes called moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical
Stress–energy tensor: stress–energy–momentum tensor or the energy–momentum tensor, is a tensor physical quantity that describes the density and flux of energy and momentum in spacetime
