Light does carry momentum. Momentum can be thought of as an object's ability to push another object due to its motion. Classically, momentum is defined as the mass of the object times the velocity of the object, p = mv. ... The momentum that light carries is so small that we don't notice it in everyday life.

The spin angular momentum (SAM) is associated with circular polarization in which every polarisation vector rotates. Each photon in a circularly polarised light carries a basic unit of SAM = ±h/2π. The sign of the SAM depends on whether the light is left- or right circularly polarised.

late 17th century: from Latin, from movimentum, from movere ‘to move’.

moment (n.)
"moment, minute; importance, weight, value" and directly from Latin momentum "movement, motion; moving power; alteration, change;" also "short time, instant" (also source of Spanish, Italian momento), contraction of *movimentum, from movere "to move" (from PIE root *meue- "to push away").
